I don't think it's me? The only one I've deleted recently was by Blacky who was drivelling on about crimewatch and how all the naughty people are black. I thought that was dodgy ground, so mag-to-gridded it (got rid).
I'm watching you, Blacky!

But if your posts were okay by decent human being conventional standards, there's no reason, as far as I'm aware, why they should've been deleted. Maybe we have a gremlin?
