there is a happy medium.
allow people to remain anonymous, but if they spend all day/every day on a particular agenda, well, that can be a problem.
I have noticed hank wood's entire purpose is to bash PDI and keith. It's pretty obvious some guy didn't just join and develop a serious beef with keith instantly - it's a troll account for one of keith's regular combatants. In cases like these, anonymous folks with an agenda clutter up the board. Then, when you give an anonymous person expert stars and he has an agenda (like txbub doing nothing but attacking keith for the last month), well, that is a problem too.
I don't know what the solution is. But lately we seem to have all the usual players, dropping dirt about each other under fake names, and it's not fun to read.
