Was griefing some base with rough coords I had seen in the chat of 64k/64k. Suddenly I was banned with the reason "hacking/speed/flying/high jump". I never hacked.

Logged into an alt account and had the same thing happen again, and about twice more after that until I was IP banned.

I can only assume I was destroying a moderator's base, and he got mad so banned me.

Now I'm gonna have to sign into a proxy every time I join the server, cheers, bitter moderator.
