I had a whole long post about the Current Unpleasantness, and then I read
Livia's post, which said it all much more cogently and succinctly. Damn you for being so smart, Livia!
The one thing I would add is that "we" are not being targeted as in fandom, but "we" as in LiveJournal. I'll repeat her central point:
Right now, Livejournal is in the unenviable position of being the landlord of a building where vandals are constantly pulling the fire alarm. Unfortunately, they must absolutely treat every fire alarm as if it were 100% real; they cannot rely on their own personal judgement and say "well, maybe there's only smoke and no fire here." Because putting illegal topics in your livejournal interests *could potentially* be interpreted as soliciting illegal activities, they must suspend journals that *are reported to them* as having illegal interests.
I would also add that including things like "pedophilia" in your user interests is not safe not just in a legal way, but in a personal security, evil people finding your LJ and thinking you're one of them kind of way. Please, even if you decide to leave LJ over recent events, think about that in the way you present yourself to the rest of the Internet from here on in.
