I sorta mentioned this in another thread: while I have no problem saying that a 'bot is a spammer and that it's banned from the forum, as was the case here, there's no real problem. If you start saying that so-and-so is banned for whatever reason, you could open yourself up to litigation, like a libel suit. While we may be more bold in the future, I don't see a need to broadcast who we banned and why -- except if the entire community (or a significant portion thereof) is affected.
SOTW is different because the owner (Harri) is in Finland. Different place, different laws, different lawyers.
