What rule did I break?
Rule #1, I imagine. It’s a subjective rule and it arguably fits. IANAM, of course, but that’s my opinion.
I see you actually started another ATMB thread called “Lighten the fuck up,” so I guess you really were under the impression that that’s an acceptable way to talk to people in this forum. It isn’t, so don’t do it again. It’s insulting and jerkish.
Why was it ok then, but not ok now?
It wasn’t OK. You got lucky and didn’t get called on it. Now you know better.
