Longevity is considered “proof” that the individual is not a troll. If one can survive here for years, it means that one has successfully demonstrated conservative thought and avoided being banned for signing up to disrupt.
I do not assume a new signup date means troll, but when a new signup starts espousing liberal crap, I remind them that everything they say (for a few years) is filtered through the troll detector.
I thought that as well.
Thanks for the response.
