I can confirm that Furry-Sneezes has had beef with me as well. I'm not sure if it's appropriate to go into detail but he and I have crossed paths.
I blocked him when i found his commentary about my existence on his forum to be rather misguided, as if he didn't particularly like my art and wanted me shunned away despite his forum enjoying my art. He lamented in a Trump-esque fashion and made up some claim that he couldn't "archive" my work because of such. His statement is odd considering I can download all kinds of work from artists who've blocked me in the intervening years of deviantArt and FurAffinity.
I've did everything but apologize to him for blocking but I never received such an apology back for his strange treatment of me. I dunno why he berates his own community members and fancies himself to be Holier Than Thou, but in light of these chat postins I... kinda hate to sound crude here but I hope karma has it's way with him in some capacity.
He has done the same to many of us. He likes a lot of our artists on PSF DA, but then says he wishes they didn't draw ponies because it isn't really art or something like that. He's done more then that, but he is super full of himself.
