I think I know what I did to make the system think I have griefed, I fell into a armadillo scute farm near central and the gate was blocked so other people don't let the armadillos out, and so my only choice was to break the fence. Of course as soon as I was out of the farm I placed the fence right back and made sure that I didn't let any armadillos out. THat is the only reason I could think of that caused me getting banned, if this is not the reason, I would like to know what caused my ban.
