I get 'nasty' Spam but as I'm only Carol, i.e. not my surname I can't 'blame' Mudcat for that. I find it hard enough to remember real names these days, never mind nicknames!
Seriously I do think that if I post something on Mudcat as Carol other catters who know me personally at least know who's actually posting it. Still each to his own and I do appreciate that there are lots of Johns, Richards etc. who post,in fact I always thought that was the main reason Catters used nicknames?
