Adventures of Queen Victoria has a good comment on some of the latest
LJ ugliness. (Also pointed to by filkertom; unfortunately the
post has been deleted.) In that post, a simple gratuitous
c.censored p.censored drew an immediate snarky
comment from an burrLJ employee 86.
From which we conclude that LJ is scrutinizing every damned post for keywords. Not really surprising; so is Google, only for a different reason. LJ has also set themselves up as sole judge, jury, and executioner of what content is permitted by their Terms of Service. OK, they can do that: it's their site. I have a permanent account, so I can't send them much of a message by not sending them any more money. (Shakes fist at sky.)
This post by technoshaman has a little more to say about it, and tibicina draws our attention to the fandom_action community for discussion of legal issues and legal action around fandom. More on the recent journal deletions here and here.
