How do y’all know if a house is self ranking

I keep seeing these posts both here and on other sororities pages accusing chapters of “self ranking” and lurking on this site. One person was counting up & down votes on all these posts, another was counting comments made on their pages, seeming to think that any rebuttal to a negative comment meant that someone from that chapter was self ranking. I know I’ve defended chapters other than my own on this site more than once so it’s not a stretch to think that others have as well. So what’s the deal? Clearly nobody knows for sure either way so why all the drama. And as for accusing people of “lurking” on this site, I have to say if you are on here enough to know how many up & down votes various posts are getting, then maybe look in the mirror???
