Thanks for this. I'm not sure if the one I was noticing is on the list or not, but it hasn't cropped up for a while. If it appears again I'll screenshot as you ask. It was an ad for a poker game featuring a woman in extremely tight clothing sprawled across a table.
A side-effect of making this site more work-safe is it seems more home-safe too!
The ads blocked are most of the ones that chronically crashed or froze Adobe Flash 10 for Linux.
