Yes, shame on the admin for that brief summary telling folks what happened. What they needed was something like a professional writer would put, like old dexy's statement as, uh, admin/host of her own site: "I knew how petty and evil-minded the admins over on AFF really are."
Wait, what? Surely not! Based on your statement about how admins should act on their sites I expected to see nothing more than "I am no longer with that site." Now, I know little of these things but from what you've told us that doesn't seem terribly professional does it? Almost, well... petty? Gosh! Petty! Yeah, we'll go with that. Maybe... and this is just speculation, you understand, maybe stating a user is removed for ToS violations, and listing the violations - much like we see in clubs and such - without adding personal ad hom attacks... maybe that is the professional way to do it?
I'm just being snarky.
