The multitude of different usernames and fake personalities she has put on over the years reminds me of Bianca Devins and makes me suspect Mary might have BPD like she did.
They have quite a bit in common:
Anorexia, fucked up family/home life, lying, constantly changing names/style to fit in or hide their pasts, whoring online, narcissism, having meltdowns over small things... proof that you HAVE to be mentally ill in order to turn to places like this for attention. Didn't Bianca beg to be raped on /soc/ before she died? Mary did the same shit with Eric and look how THAT ended.
