I remember a less that fun experience with D3ATHCAT I once had on my friend's fortwars.
So basically, I was building a fort that was significantly bigger and safer than the other forts of the server, and deathcat asks if he can join my team, to which I say no (I only ally with people I know IRL). Later, when I'm fighting, he asks to join again and I say no again. About a minute later, he comes to my base in a helicopter, which i proceed to blow up. He gets mad at my doing that, claiming that he came in peace. I understood what he was doing, but the fact that he did it in spite of my saying "no" only made me want to blow him up more. This happens a couple more times, and he gets madder each time. Finally, the server is shut down, and we have a long argument over IRC, which I have not pictures of because I didn't know how to screencap IRC's.
Do you remember this, D3ATHCAT? it was on Revolver_Ocelot's server in I think November.
