Since I knew Matt back when he was 16 or 17, he couldn't be that blatant. But he did let the SLJB mods delete posts of mine that were entirely on topic. And one night he did ban me.
I yelled at him in PMs for awhile, and he removed the ban a few hours later. I'm sure he knew that if he didn't, I'd have started complaining to the other admins, and they'd have believed me.
