I just used caps for emphasis, sorry bout that. Yes, I know that they are on two different servers. The griefing one happened to be also caused by lag, but this time my old pc was lagging horribly, so I accidently broke some blocks of someones house. I've already cleared this up with the admins, and they are looking into the problem further. The house has since been fixed and the owner of the house and I are now quite close friends.
