Although Ive never seen this side of Frozen before, he's usually a pretty "chill" (HAHAHA) guy about things. He only gets angry when you take him the wrong way. This IRC is definitely drama worthy for Frozen's reaction. However in my opinion the reason he was angry at you was pretty much your own fault.
All forms of aimbot created for Blockland are useless and dumb because each one of them have several bugs.
If you have no actual text stating or any confession made from Frozen HIMSELF where he says he used aimbot, then you really still can't be sure. Just be because you were "watching him and his head followed your every move" that still doesn't prove anything except that either
A. You weren't watching him correctly or you based your ban off of only a sliver of evidence OR
B. Frozen is an experienced Knife TDM player and his skill surpassed yours so much that you werent used to seeing something that looked so much like an aimbot at work.
Due to the text overload I didn't read all of the chat, but I got the main intent of the drama. I'm sorry if my lack of reading skill is making me falsely accuse you of anything, you can point out my mistakes.
