I ended up just doing that for a while. I had captured his largest village besides his capital, which borders all his other villages, so I was farming all of his other villages from the one. But he couldn't defend himself against the 20 legs. that I had at the time so he started this crap about hacking my account.
I didn't want to get him banned. I would much rather just farm the crap out of him. But I wanted to make sure that he couldn't hack my account too. So, maybe he's only banned temporarily...
