Thought I’d raise this as it doesn’t look great!
Three times recently I’ve had a mumsnet “suggested for you” post on my Facebook timeline, clicked on it, and got the thread deleted message. The one I was just shown was about a dance class, it’s still on the mumsnet Facebook page and being “suggested” to potential users (I don’t follow mumsnet on Facebook). I dare say there’s a fair crossover in terms of threads that work people up so Facebook promote them, and threads that work people up because they’re by trolls!
