Could it be possible to hide sponsored threads? At least individually if not the whole forum (I see why that wouldn't be ideal!)
Right now there's a sponsored thread asking for how your child has been a good sibling. My child isn't a sibling because since her I've lost 4 pregnancies. So not only can I not win the money, since I'm lacking anecdotes, but I also could do without the reminder every time I log in to mumsnet
