I always tell people to treat Facebook as if every person you ever meet will be able to see it. It's more or less my public persona. Twitter is more anonymous.
Amen. Once you upload it, you should just assume it’s out there forever. It’s probably worth assuming that virtually all anonymity can be pierced, if not now then within a decade or two.
With a few exceptions, anonymity online is ephemeral at best, subject to the motivation of the person/org trying to deanonymize you.
How did you arrive at that conclusion? I assume Twitter retains everything as well (even "deleted" tweets) and it's all associated with an email address. Or did you mean it in the sense that far fewer people have a Twitter account?
I used to believe Twitter was better. But once you're above a certain number of active (i.e. publicly retweeting) followers there's a pretty high chance that your tweets will end up in the feed that is used to generate the twitter stream archives:
These are tar files that contain bz2 compressed newline separated twitter events as json. These include deletion events as well, so you can for instance easily estimate the time an auto-deleter is set to.
Yes, they're huge archives, but you could still probably process a year of these for particular targets for under $10 on EC2.
Whilst I'm impressed with archive team's efforts, I would be surprised if there aren't some commercial twitter stream consumers that absolutely dwarf this.
Treat everything you put on twitter as public forever and you won't go too far wrong.
Why would you ever believe it was private? I think Twitter is better because everything is explicitly public, rather than dishonestly pretending it's private.
Well, I never said I did believe it was private. When I said better, I should really have said better behaved in respect to deletions.
Because of the twitter stream APIs it's not. But there does seem to be a strange presumption amongst users that deleted tweets are gone from public view and cannot resurface. There are people who use tweets in all manner of ways that they really weren't designed for, some of which involve deleting them after a few minutes.
Many a public figure uses these tweet deletion apps. Some do it for more honest reasons (status count limits -- do they still exist?), others do it to limit their exposure.
In the UK at least, there have been cases of libel where either the claimant or the defendant depended upon twitter and in at least one of these the court admitted the claimant had an unfair advantage by forgetting about having a tweet deletion app attached to their account. The case proceeded and the claimant won despite the acknowledged advantage. To some, this may be seen as a clear message that in the eyes of the judiciary it's okay to delete tweets (evidence) as long as it was through an auto deletion app and the individual concerned forgot about its existence.
I would not at all be surprised if some lawyers to the rich quietly suggest they install a tweet deletion app as general advice upon instruction.
Twitter is more about finding your own social graph of people you find interesting than friends/family/coworkers like Facebook is primarily about. I could have a completely anonymous persona on Twitter and get all the same content. I could use a fake name on Facebook but it wouldn't make as much sense, and I could be reverse engineered with some accuracy from just my social graph. Your family is going to tag you as family, etc. The other non family and friends content on Facebook is more watered down than on Twitter and Facebook wouldn't be worth using for that alone.
