It's getting really boring when a number of posters repeatedly keep dissecting threads and questioning how genuine the OP is, often leaving a lot of ill feeling in their wake. Seen a lot of it around lately - it is becoming an epidemic!
The MN policy on trolls says:
"we would rather Mumsnet erred on the side of giving folks the benefit of the doubt and risked being made to look a bit foolish than pounce on someone who turns out to be genuinely in need of help. We hope you agree"
So perhaps MN HQ would consider banishing the repeat offenders to some poisonous cesspit of malice? They wouldn't be missed.
