Chris was let into the con for free by the higher ups, he caused problems, they warned him (whether in person or online is kinda irrelevant because they didn't have to, but it seems like in person), he kept causing problems, they told him to GTFO. There is an argument that people should have just told Chris off in person rather than reporting it to management, but cons attract spergs who don't do conflict, and, autism or not, Chris is a 36 year old man who has been pulling this shit and being told to stop for over a decade. It sucks, and millenials can be snowflakey as fuck, but society has decided that slobbering on people's faces when they don't want it is not ok, and the con is gonna protect their ass when multiple people come up to them complaining that a hobo in a wig is acting inappropriately.
