My two cents (not worth very much nowadays, I am afraid): I have not looked at the collections but like others, there simply have to be some girlie stuff, scantily clad beauties, ripped men, etc. I suppose these have place in clipart collections, someone might make use of them and not necessarily in harmful ways.
I would like to see all the sexist and sexy stuff de-emphasized. I am more concerned about the ad-pictures that will adorn our technical sites (and I have complained about some of it). I am also concerned about the prevalence of foul language in a professional forum. I think we can do better.
