I've been deleted several times, mostly for obvious troll hunting. I try to avoid doing that these days, although don't always succeed!
I've been banned once, which made me absolutely furious. MN had decided to partner with a company that was launching a 'breastfeeding biscuit', which had no more helpful nutrition than a straightforward digestive. In the thread, started by someone from MNHQ, I posted 'what the actual fuck do you think you're doing, MNHQ?' or words to that effect. And that got me not just deleted but also banned for a PA. All of which was rather awkward because that very day I was kicking off a new Bootcamp!
