I guess the question is what to do about this jerk? Beav pointed out one option as to how to block a person's posts. I don't know if it works or not. There is so much of this site I don't know about. May be worth a try and if others don't quote him, half the battle is won.
As for having a moderator, I would vote no. First off it would be a full time job to keep up with all the posts in all the blogs. Then, if you combined one post into another blog and that poster would not be able to find his post and that would only lead to discourse. More so than the combining would be beneficial. Even when I play the Music game I try not to use a name of a song that was used within the past few pages. I posted a question in the "Question of the day" blog and went back 10 pages to see if it was asked before. Found nothing so I asked it. We, I think, can moderate ourselves if we only choose to.
I came to this site as a Ryan Newman and Tony Stewart fan and it took me awhile to learn the people and procedures. Well Ryan left but I stuck around because I find the place fun and like to compete in the pick-em games. (not very good at it but still fun) More recently I've enjoyed playing Tony's coin game. Enjoyed??? Well yeah, I guess so. If I get one more one I'll....
As I read through the posts I see OCD and do not know what it means. I went to "Internet Slang.com" and it means Obsessive Compulsion Disorder and has no other meaning. Is that right? Doesn't seem to fit some of the sentences that I see it used. But that's okay.
In conclusion, I do not have an answer as most of you don't either. I would just ignore and don't feed any abusive poster. I found this quote that seems appropriate: "People can be cruel, and they will be. People can hurt you, break your heart and they will. But only you can let them keep hurting you..."
And that's my nickel's worth.
