You have to be very new to the scene if you honestly think calling people out is a new thing, in the FGC even. The same things happened on SRK way back when as well. You should google around about Duc Do and the shit he did, priceless stuff man. Your most people only posting to stop bad rumors is also wrong as well, but once again man you're free to believe what you want, but it really sounds like you're gasping for straws~
I can completely understand not liking the style or format of the site and how unfiltered it is, it's not for everyone and I'll be the first to say reddit is an ugly 1997 looking website, but to say rkappa is bad because one dude posted a thread about sherry sleeping with noel isn't really a case to hate something.
But I digress, you're free to your opinion on the site and it's clear nothing I can say will change your mind~
