Upon reading that chat log I decided it was time to pull the plug and ban him from chat for good. HeeroYuey had been warned repeatedly over the course of three months to behave, he simply refused to do so. He ignored all of the chances we gave him to behave. It's not that hard.
I certainly hope this clears things up for some of you. When we ban someone from chat, we always have a reason. It may not be apparent to the rest of you, but it is there.
So like I said at the beginning of this post, the ban will not be reversed. Quite a few mods talked to and explained to him that he needed to not do certain things, like swearing, insulting others, being vulgar, etc.
If there are any questions, feel free to pm me or to include them in the comments. I'll do my best to answer all of them.
