So I contact the staff that kicked you, and this is what he sent me in regards to what happened:
You gave him the most obvious web attack threat if I've ever seen one, you're pretty lucky you weren't permanently banned for doing that. Moral of the story? Don't threaten people, especially a DDOS threat. We take these very seriously. I'm going to lock this thread, you know what you've done wrong. Don't do this again, other wise you will most likely be permanently banned. Also, threatening to come on alts if you're banned is only making you look worse.
