That happens, but sometimes I've seen it happen as an overreaction to excesses taken by those posting stuff. People need to remember that this is a TYPED format, and therefore trying to claim that something just "slipped" doesn't work. Before this posting ends up where everyone can read it, I still have to finish typing, and THEN hit "submit".
The best rule of thumb is, if we're self disciplined, we won't need to be externally disciplined.
That doesn't excuse the overly authoritarian moderators, and I haven't done much over on the KS forums since coming here (this is a much more helpful and fun group), so I missed pretty much all of what went on.
The trick is always finding a balance between effectively keeping things under control, and allowing people enough creative freedom to enjoy themselves.
