I think we're seeing an enterprising scam to get bitcoins here.

..right... nice way to get that bitcoin donation address spread around.
As the Anons don't even know each other.. who's to keep the owner of that bitcoin address accountable?
It could be anybody posting their address as Anonymous's address. Great idea. Get Anonymous mad at you.
Judging from the genius regularly displayed by posters in this forum, I wouldn't put it past someone to try it.
