It's pointless reporting generally though. Tends to be ignored unless it's blatant trolling.
I dream of a hide poster button. I can't even come here for support anymore because that twat always pops up on those threads and makes me feel even more shit than I already did. I can try to ignore but when the thread descends into everyone who is normal vs HMOO, you can't miss it. So every thread gets abandoned. Now I can only stay on the light stuff and it's not fair that my use of a forum is hampered by someone who just wants to spread hurt. I've had some of the best advice here and now I can't ask for more because she appears bleating about how I made my choices so it's all my fault.
I know MNHQ don't care really and it's the old don't give too much of yourself thing but if one user makes it like this for a lot of people, something should be done.
I remember when posters have been banned or suspended for jumping on threads to make people feel like shit so I don't see why this isn't the same. For months (years) she has targeted benefit threads, lone parent threads and child maintenance threads with the sole aim of spreading hate. I've seen the OP of these threads politely ask her to stop but she continues. Her own life is obviously shit so she needs to make everyone else feel shit but it's not on.
This is the only thing that other forums have above mumsnet tbh. The ignore or hide function! It would definitely encourage less cuntish behaviour for the sake of it.
