Morning, What thread was it Naomi? I'll see if I can dig it up for you.
As for why - we can suspend, and do so when a user has contributed a useful/interesting question. BUT, when a user has a majority of nasty questions we'll often have to ban them (to remove ALL those questions at once). Individually pruning isn't always the best use of our time, and as such, there is occasional collateral damage.
I do find it funny that when I suggest a few guidelines for debate everyone is suddenly "Stifled" - especially when I'm still asking for your opinions about it! (Over here if you want to throw in your tuppence-worth:

All the best,
Spare Ed
