I think some readers just don't know me like others do.
I read quite a few posts before I started joining in, and J08's posts certainly stood out, but made me laugh. The trouble is, it's so easy to take things to heart when it is all written down, even with the use of smilies. What can be seen as a little blunt by one person, is seen as downright rude by another. I moderate a forum elsewhere, and it isn't easy. If one person wasn't banned, then maybe half a dozen would leave. In the end we decided that we would only warn/ban people for racist remarks and anything sexually offensive, ie harassment of a member by another in a stalking sort of way. If someone started up a potentially inflammatory thread, people can choose not to read them, after all.
To all the moderators on here, I would say that you need variety, otherwise you can end up with everyone agreeing, too afraid to discuss anything other than the weather, and a very boring board so that everyone leaves anyway.
