I'm sure most of you are aware of this, but I'm feeling the need to spread the word. Apparently LJ is now permanently deleting what they consider 'questionable content' without warning and banning the users. This doesn't necessarily mean illegal content. Two people were banned on Friday for posting Harry Potter smut art (smut between consenting adults, no less.) The LJ management are basically reserving the right to delete anything they consider too sexual if it 'has no artistic or literary value.' They're also refusing to define 'questionable content' or how they're judging literary and artistic merit.
