Also, sometimes people add me to their friends lists and I don't want to add them back. If they have a username that I don't want appearing on my userinfo, I'll ban them. That way, they won't appear on my userinfo and they won't be able to comment on my journal. If you think you were banned unjustly or by mistake, email me and fill in your username on the first line and on the next line, explain why you think you should be unbanned.
Serial adders will also be banned. I created anti_adder, a journal that is dedicated to the war on serial adders. I can add or remove anyone from the list of serial adders, so do not anger me.
