The bans probably shouldn't have been public and it makes sense that there is no list anymore. However, shouldn't people be able to find out how long that they've been banned?
(Not that I'm complaining, I'd bet that every ban was well-deserved.)
According to relics post, they only ban when they're 100% sure it's deserved. Although words are just words and are different to every person. So take with it what you will.
