I don't know his past posting history, but if someone's first instinct is to battle everyone who crosses their path, including engaging in fights over timestamps - that's a huge red flag. No one has the time to deal with that. If your timestamp is off, most people ask, "How can I fix my timestamp", not get your **** together and then call people internet tough guys when they wonder what the heck they are talking about. There was no sign of patience or grace while we try and sort everything out. I wish him the best, but he wasn't helping the current situation (unlike the vast majority of newcomers who have been really awesome so far).
