What a long-winded post of absolutely nothing.
You got paid for actual joins, didn't you? Nothing in your posts suggests otherwise, so what you're really complaining about is some random reporting error of archived data that no one else in this thread has encountered. I've seen things like this from time to time and they go away all by themselves.
I am sure that every username in my password file has come from a legitimate (i.e. paid) join. No other statistic matters.
You seem to have been in this business long enough to realize that not every support staff member is aware of everything that goes on, or is even competent. You know, the other day I asked a guy at Home Depot where something was and he pointed me to the exact opposite side of the store than he should have. I'm sure he was running some kind of scam.
