Sure they can.... I’m betting they are not paid minimum way, but more like 25 to 45 dollars an hour.
You must not be able to read people’s posts very well, My guess is that you have not outed a lot of trolls in your time here. For a poster to try and get involved in a deep passionate way on a passionate subject here at FR and do that under a variety of names on the same threads is impossible. I don’t even know why you would try to sell such a UFO type idea.
Spend some time reading those two years worth of threads and see if you think you can spot such a poster, much less support your claim that it was and is, a half dozen people under hundreds of names.
If you find two names that you think are one person then read those freeper’s individual posting histories and see if you still think that.
