I used to know two women who owned a website about a specific breed of dogs. They were both banned from several similar websites prior to opening their own site, primarily for eternally causing trouble and insulting other members.

Their co-owned site never particularly caught-on and a short time later the two parted ways with the woman who left telling everyone her ex-friend was so contentious she had joined the site under multiple usernames so she could argue with herself!!

I think I'd enjoy chatting with myself, too. I would say I'd be good company for myself but I've been so down in the dumps this week I don't think I could stand myself!
