I see nothing wrong with a post being controversial. They often make for interesting debates. Just to mention an example of what I am talking about: in a heated debate people may resort to personal attacks and trolling. I have reported those before just to hear the crickets, so I just don't bother anymore.
Most likely your definition of "personal attacks" and/or trolling is different from ours.
In the good old days, before we switched over to Xenforo, it was easy to go over a members reports, that is the reports that they've made and sent us, to check something like this out.
There have been times in the past that we've had members come out into the open forums like you just did and say "Well, I made reports and reports and nothing happened, blah blah blah blah blah", and then it turns out they never actually made any reports, or if they did it was one or two over the course of however many years and about something that may have upset them but wasn't actually a rule violation.
You're saying here that you reported actual personal attacks and trolling and nothing was done about it. I seriously doubt that.
But I'll give you a chance to verify it.
How about sending me a conversation message telling me who you reported along with a rough timeframe and I'll go check it out.
