I would take what Soda has posted and go a step further. Two steps, one in two different directions.
There are those who do the same to other band members, current and former, and that is not acceptable, either. I myself was guilty of that and while I've corrected that, I hope it shows. I don't agree with everything any of them do, but saying 'wow, that wasn't the best way to word that' is a lot better than 'he's an idiot.'
The other thing is personally attacking anyone on the board, and especially someone who is defending someone else or who has a different opinion than you. A comment like 'anyone who can't see that is just stupid' or 'your opinion doesn't count' is inappropriate.
I hesitate to call anyone a 'hater'. I will go on record in asking that the post of the Amazon review be removed as it violates our Terms of Service. Quoting an inappropriate source is the same as posting it ourselves. I wouldn't want guests or brand new members to come here and think it's acceptable. In going through Twitter searches and Google alerts, I've avoided even posting links that violate our TOS by flaming any of the band members. I don't always read them in-depth so if anyone sees one that should be removed, let me know.
