Ideally the mods would like to keep the forum to a narrow demographic for friends and others who share their sensibilities. You might encounter someone who is frequently rude, offensive and wonder why he [he mainly] is never banned. You might encounter others who are banned just because he/she ruffles some feathers. Draw your own conclusions. If you can annoy people who are set in their ways, it should usually be a good thing which should be encouraged for a healthy forum. otherwise it can be ahhhh! zzzzzzzzzzz
Could you illustrate the above observation with some evidence?
