Sometimes the ban is just 'replying to off-topic threads'. Sometimes 'replying to off-topic posts'- That's the most random usage of the ban function.
Also every board have had problems with moderation banning over private interests (see: russian janny/mod).
My pass is from 2017 and you know, you can add up a lot of bans in the span of 7 years.
