Depends who the opposition is ! You have your genuine support and then you have your bigots, on both sides. The former you can shoot the breeze with, the latter are beyond help.
I block people for one reason - anyone I suspect of being a reporter gets the block. Hence why my account has lasted so long this time. Lost 3 previously and then decided enough was enough. Set up new account, blocked any known clipes, hey presto, account still going strong. One downside, you can block from answering your own Q's, but they will still clipe on your answers to others.........got more violations in 4 days of the last week than I had in the previous 2 months, by sheer coincidence certain users had come out of hiding and used the forum for the first time in ages.
