There are a handful of posters who pop up fairly regularly and honestly I've never agreed with a single word they have written, they have some very offensive views and pretty much every time I read one of their posts it infuriates me.
I'll be enjoying a thread then these posters will pop up, I'll see their usernames and I'll instantly think god that's this thread ruined then and leave. It happens enough to make using Mumsnet become far less appealing.
Wouldn't it be great if we could block posters and just carry on enjoying threads with their contributions blacked out like you can on Facebook comment threads?
