I’d make up user names that were puns on the names of other posters and argue with them, inventing crazy backstories as I went along. You know, oft bears cats and Unauthorized Cinnabon and SenorBeet…thought I think I’m just going to stick with those for now, because I’m pretty sure they’ll think it’s funny.
Imply that I was the sock of somebody else --somebody I wanted to get banned-- because they had the audacity to disagree with me about something political.
I read another (news/technical) board where registered users are also allowed to post anonymously.
Anon posts need to be moderated more rigorously, but but they actually get used by normal users to (a) post comments that must not be traced back to their real job, and (b) post arguable opinions that they do not wish to argue about. 95%-98% of all comments are pasted with a user name, because, I gues, although you can post anonymously, wheres the fun in that?
