>but apparently there are some folks out there who are enjoying pushing the limit of exactly how much pornography they can incorporate into wikipedia.

Bingo. I would even go as far as to say that wiki's have this way of attracting entire sub-cultures of contributors who enjoy sneaking such things in wherever they can shoe-horn them. (See: Tvtropes.) On the one hand I support wikipedia's position that they shouldn't censor the articles. But on the other hand I don't see limiting this subtle vandalism as censorship. It's more of quality control than anything else.
