You might want to post your proof links again to somewhere else as all of them are "502 Bad Gateway". Also move to scam accusations.

It's really hard to say anything about your case without proof, but memefying your serious accusations into nick doesn't really give me good impression and i am almost certain that there are not going to be racist bone on those proofs even before seeing them.

I would totally block someone if they turned tech glitch issue to racism accusations. There are real people working behind help desks and they don't have to take all the crap.
