Your account was penalized, probably because of past involvement in flamewars. But your recent history looks fine, so I've taken the penalty off now.
Also, it's not clear how to do it well. I do have some ideas which I'd like to try someday. Here's one: people work well with feedback loops, so telling them that they're penalized and giving them a way to fix it could be a good thing. Unfortunately, it could also just be awful. This place is always one step away from sudden decline, and when walking near a precipice one wants to step carefully.
