how did you know that he was banned?
I'd been cautioning him to temper his messages, taking the high road, making references to my own incidents a couple years ago with someone else who continually attacked me to the detriment of the entire site. As a result, he notified me when Lazeez penalized him. I essentially told him: don't sweat it, take it easy, ease off and maintain communication with individual authors, but avoid objectionable content or overly harsh criticisms (good advice, since he was looking for advice of editing other author's work).
Since then, both he and REP100 gave me the full list of documentation on the forum, their private communications and Lazeez.
