AOL Just Did the Unthinkable – Boycott AOL?

Thank you, Google for resisting the DOJ’s effort to obtain user search data. You put up a good fight to protect our privacy, and you won. Too bad it was all in vain.

AOL, in blatant violation of its users privacy just released the log of 3 month’s worth of searches by 650,000 users. Not to the DOJ, but for open download by anyone. The claim:

“This collection is distributed for non-commercial research use only. Any application of this collection for commercial purposes is STRICTLY PROHIBITED”

Prohibited. Yeah, right.  As if they could control it. The data is supposedly “anonymized”, which in AOL-speak means the screen-name is replaced by a unique user number. Anyone a little bit familiar with data mining knows what this means, and obviously some commenters on the AOL blog have already put two and two together, “outing” certain users whose identity was easy to find based on the search patterns. I don’t even want to think what data mining pro’s will do with this.

AOL, you betrayed your users. If they are any smart, they will boycott your services.

Update #1 (8/6): I’m going out on a limb here with this prediction: as they realize the magnitude of what they did (or if they don’t, due to the PR nightmare) AOL will apologize, the fingerpointing starts and heads will roll. They will remove the download link. Not before anyone who wanted the data will have obtained it though.

Update #2 (8/6): TechCrunch further elaborates on the “utter stupidity” of this move by AOL:”

“The data includes personal names, addresses, social security numbers and everything else someone might type into a search box. The most serious problem is the fact that many people often search on their own name, or those of their friends and family, to see what information is available about them on the net. Combine these ego searches with porn queries and you have a serious embarrassment. Combine them with “buy ecstasy” and you have evidence of a crime. Combine it with an address, social security number, etc., and you have an identity theft waiting to happen. The possibilities are endless.

Update #3 (8/6): The download link leads to a blank page. Perhaps AOL Exec’s are waking up… I wish all my predictions (see the first update above) would materialize this fast.   I wonder if there will be a black market for the “limited edition” downloaded dataset… eBay, anyone?

Update #4 (8/6): Dennis pondering about possible ramifications, partly based on our Skype IM:

  1. Zoli estimates maybe 1,500-2,000 downloads by the time AOL woke up to what theyโ€™d done. Whatโ€™s the real number?
  2. How long was the file in the wild?
  3. Could illicit copies end up on eBay?
  4. Could market data derived from the file end up on eBay or as part

    of a market intelligence offering? Almost certainly the second if not

    the first.

  5. What will be the impact on AOLs stock price?
  6. Might shorters speculate on the impact?
  7. What about a class action lawsuit? For once I think there are

    decent grounds for one of the ambulance chasers to send out its hit

    squad – they may even get what they need from the file

  8. Will AOL be able to track who got the file?
  9. What is the potential for wholesale identity theft among those 650,000 AOL users?

Update #5 (8/6): The last thing I expected was to find myself deleting comments; but this situation forced me to. A commenter provided a link to his site where he put up the file for anyone to download. I know the cat is out of the bag, and there will be several other sites, but at least I don’t want to actively promote making a bad situation even worse. Since I can’t edit comments, my only choice was to delete it.

Update #6 (8/7): ZDNet agrees: “People will be boycotting the company because of their blatent disregard for the privacy of users.”
The news is out on Infoworld, was well as mainstream news media all the way to Korea.

Update #7 (8/7):  AOL responded by email to John Battelle, also quoted at SiliconBeat.  “The summary: Man, did we screw up.

    Reality check:

    1. anonymized search logs are perfectly legal to distribute, and in compliance with all rules

    2. anonymized Query logs are widely used in research, only that people have to specifically license it from google / yahoo etc, by working for them / with them.

    3, Query logs are an invaluable commodity for the research community. Without them all web research is like trying to design something without having any requirements to cater to (tailoring clothes without measurements!).

    4. Big players like Google and Yahoo DO NOT share this with the research community, using it internally to maintain their monopoly.

    Regarding comparisons with Google:

    1. technically, the “Google Trends” service is also an exposed view of their search logs

    2. Google Research also released internal data on the same day, for the same reason as AOL Research. Maybe you should produce blog post worshipping Google about this.

    3. Google not only studies what you search for, it also studies every bit of your email at Gmail, your calendar, and your IM conversations. Anyone who knows how to de-anonymize these search logs can also use adsense to deanonymize your email (using impression statistics).

    I’m myself am totally against AOL and it’s spammy nature of shoving their CDs around to everyone. However, I’m also against ignorant Google-fanatism, hence this comment. Imagine the advances in search technology that this data will bring. Why should a few kilobytes of data hurt?

  10. Stunning Privacy Breach by AOL

    While most reports have commented on personally identifiable information in the queries, there’s a greater risk of identification due to ability to link “questionable” queries to requests to government web sites.

  11. Anonymous says

    The real threat to privacy isn’t as much the personal information as the presence of timestamps. That allows potentially any query, and thus user, to be tracked back to IP address. Especially if government owned sites are involved.

    Apart from any ethical issues, AOL has breached its contract with its users. This disclosure contradicts AOL’s own privacy policy, which names search data as being part of a user’s network information, says that a user’s network information will only be disclosed as described in the privacy policy, and makes no mention of just publishing the data for public research. (There is a mention of using the data for researching use of the AOL network, but that’s not the same as letting the whole world do that).

    1) There will not be a black market for this data on ebay. Predictably, it is already mirrored and torrented.

    2) searching for drugs or words with drug connotations is not a crime. I doubt there is even probable cause for any police force to get a warrant. At this point, I could type “buy ecstasy” and this page might be the top hit.

    3) Google has released 6 DVDs worth of 5-gram search terms. They will not give a hoot about this “large” dataset

    4) AOL still has users?

    What Google did was release information informing everyone of how often everything is searched for – not who searched for it. There is absolutely no user specific information available from Google’s (soon to be) published data and it should come to no surprise if “porn” tops the list of words searched for. On the other hand, maybe some names are searched for often and it shouldn’t be too much of a surprise to see some in the list, but that doesn’t mean that Steve Jobs or Bill Gates are typing their own names into Google.

    Hey, even with the AOL data there’s still an amount of deniability, but it’s appalling that anyone should be put in the position of having to deny anything. And the idea of a “unique” user ID means that at some point, somewhere AOL probably have a file that says how that corresponds to the user that did the search. If that file ever gets out, then all anonimity has been completely lost.

  20. It might well be that searching for drugs on AOL is not a crime, but after reading this: , I wouldn’t be so sure.

    AOL will instead scapegoat the people who mirrored the data. They will use their PR team, dupe a government agency into denouncing the “dangerous” linkers, file a lawsuit, and drive the media to villainizing anyone who dared mention *their* bungle as hackers.

    It’s been done before:

    Kill the messenger, and all you get is quiet.

    As long as the public falls for this sort of distraction tactic, they will deserve the world of corporate secrecy and cover ups they get.

  26. Anonymous says

    The information in the database is _not_ anonymized. There are unique ID’s associated with each query, making it very possible to relate the identity of any given person in this database to their search query. The table that relates the anonymous ID’s to the users isn’t out in public – Yet. But I guarantee that information exists somewhere. You better believe it can be subpoenaed if a law enforcement agency that gets their hands on this database decides to go on a fishing expedition. I hope no innocent people on this list were doing research on questionable subjects or else they can say hello to “probable cause”.

  28. Reporting about it is good. Distributing it to the public is bad–as bad as what AOL did. In fact, it is what AOL did. Yes, the data’s already out there, but that doesn’t mean the users no longer have rights. Personally, I say boycott everyone who intentionally distributes this data. (e.g., Slashdot)
