I infollowed SM ages ago for the similar reasons, I just couldn't relate to her any longer and it was all just a bit 'girl gang' (which is why I unfollowed loads of them!). But I like her sweatshirts and do own a couple (they are comfy and good quality).
I missed the comments as she'd deleted them by the time I checked, sounds like it was a very good move on her part if there was a lot of mumsnet vitriol.
LOL at the 'who actually uses forums' - what the actual fuck does she think the comments under her 'content' are?? Is she mistaking it for a whatsapp group of her personal friends? No - it's a forum of people, who don't know each other, talking.
