The best part is that they're not just banning people, but one at least one server they're putting up in-character messages. I don't know what most of them are (I've only found the one example so far) but I like the one from the blog post:
Tchar’zanek has ordered the slaughter of [Spammer] and all others of his kind who weaken the Raven Host by providing wealth and power to the unworthy
As some of the commenters have said, I can see it being great fun to see those when you're used to MMOs being full of gold sellers spamming people, and the fact that they're being creative with the in-character messages is just great
