Facebook Whitewalling is an emerging teen technique to control Facebook privacy: it is the act of logging into Facebook, but deactivating your account each time you logout, then re-activating it when you login, and then deactivating it again when you logout, and so on.
This is a trend that Danah Boyd has recently identified.
The idea is that, without an account on Facebook, you can’t be tagged in any images or other users status updates or check-ins that you don’t want to be.
This means that you control what presence you have on the social network.
It is, actually, a pretty ingenious way of putting power back into the hands of the individual users. What’s disappointing of course, is that Facebook doesn’t have an explicit “don’t tag me!” function already built in. Maybe this new user behaviour will see this shift.
Interestingly, Drew Benvie is experimenting with this and recently wrote about it here. I’m really intrigued and will be watching keenly to see what he makes of his extremely interesting process.
