He wrote an extremely inflammatory and disrespectful public post. In it, he called people who left condolences for Walkazo, a valued community member who passed on a few years ago, "scum" based on petty standards. If he deemed someone's condolences "poorly written", he labeled them as fake mourners incapable of genuine emotion.
Basically he had the audacity to review and rate the validity of people expressing their grief for a friend who passed away, and make himself the judge of whether they were doing it "correctly".
Then he wrote a damage control apology where he gleefully continued using a silly disparaging name he made up for the people he called scum, and said he intended to write more posts like that in the future.
