I'm not being mean here, but... honestly, I'm gonna guess that the 99.999% of the folks here probably don't care about what folks got in trouble for... all that really matters is that generally, folks should realize that text does not convey the visual and audible nuances of a verbal face to face communication, so react accordingly when reading something you may disagree with... use emoticons when possible, it's what they were invented for.
add to that "treat others as you would have yourself treated" along with "dont say anything in text that would get your ass beat down if you said it to someones face" and you've got some good rules to live by
your idea is interesting, but its really something that should have been started when the site opened, as opposed to 3 years and 14K+ members worth of records later.
Mods are an unpaid position, and I cant thik of any one of us, Mods or Admin that would be remotely interested in siting down and wasting hours on such a project.
and on that, aside from the HUGE amount of spammers that we've banned, I'm going to offhand say that there have been less than 30 participating members banned permanently for cause.
for cause is generally:
excessive trolling
sock puppetry
personal attacks and harassment
illegal activity
total refusal to abide by any forum rules
less than 30 from 14K+ members ... I'd say the staff and mods here are more than evenhanded... and this comes from me having almost 10 years of mod work on another, MUCH more "wild west style" board, BEFORE this site even opened.
