I can sorta sympathise with racer here. My first account got devoured by the forums and I got an inevitable ban for a stupid topic I made back in 2009.
I gave the forums a rest and stalked it for a while and I came back with a better understanding of the forums' behavior and adapted. While I do see racer was out of line, it was antagonised by the forums (forcing me to advise they avoid posting). I admit, people expect everyone to have some form of intelligence and understanding when they begin posting, but not everyone grasps that concept, which is where Black should have initially warned racer about the forums before this topic began.
I admit, to new users, the forum is a scarry yet facinating place where users can communicate with one another and can share their content involving blockland; however, there are dark sides of the forum where players become hostile and can tear some one who is unfamiliar appart.
TD;DR - I understand his position, but he definitly was out of line.
