Obsessively and aggressively devoted to a niche hobby? Check (sonic/trains)
Injects self into social situations to share said hobby, even if nobody else cares? Check (sonichu on everything/train pictures on everything)
Creepily enthusiastic about meeting/dating women? Check (attraction sign/rapejeep)
Unwarranted self importance annoys everyone, makes himself a known nuisance in social settings until banned? Check (GameStop chucks him/Colebrookdale RR chucks him)
Claims to not know why they were banned, credits it to a conspiracy to pick on them? Check (Dirty Michael Snyder!/Drty Board of Directors!)
Cannot grasp above concept even when drug into court? Check (Chris' multiple convictions/Shaner's pending convictions)
Easily identifiable by consistent misspellings and catch phrases that make it impossible for them to hide? Check (noviphobia!/privet detective!!)
Sets up phony social media/web presences to get revenge? Check ( Making comics where his enemies get theirs/ fake FB accounts w/ dozens of sock puppets)
Believes they have skill in an art/craft ability far beyond displayed level? Check (art/photography)
Two total strangers who've never met, but exhibit the same patterns of behaviors, almost to a "T" amazing really.
