Welcome to PC ... you won't have those types of antics much around here.
There is one particular "support site" that has admin just like you described. Best stay away from there, and be here.
But we do have some guidelines to help you fit in. If you have an issue (rather than a legitimate question) with something admin is doing or saying, then you do need to PM them. We try to keep our disagreements private, so as not to trigger or upset the rest of the site.
