I don't care about the personal lives of others.
In the case of Daemon / Castiel I think he pretty much summed up his attitude from the start therefore he would not have cared anything about what rules were in place on a site like this.
Generally, I don't see what is so hard to do in adjusting to this site unless you are naturally off with grammar and being able to 'talk' about things. For me its so easy because I don't step on anyone's toes by trying to dictate what must be said or how it must be done, etc. Isn't that how it should be anywhere you go? Why join a place only to start off by making yourself as unapproachable as possible and criticizing others?
