All signs point towards 'sourpuss' being a dedicated troll account. Looking through their submission history it's quite plain how they've peppered their submissions with deliberately inflammatory content, and then never commented on a single one. Not saying that these green accounts are their sockpuppets necessarily, but their account is certainly a lightning-rod for lulz.

Whatever the case may be, submissions like this boil down to drama and personal conjecture rather than intellectual gratification. I'll keep flagging them until their submission quality improves.
