I was not sure before, and only got clarification recently - that's why the ban was so retroactive - real life trolling on the forums, particularly the posting of images against a person's consent, can be punishable by in-game bans. People have been permabanned for this before. It's that serious.
Don't post pictures of other people in the community here.
The ban will stay up for a while, but won't be permanent. I will post again with a definite unban date.
