I support this in general
I don't think this is a censorship issue, nor do I think it's preferential treatment. I expect to see these apps (or some of them, anyway) return in the future, corralled into their own place in the app store. As it was, you had one developer distributing almost 500 apps of separate girls in bikinis. This is development? I've worked with models. They will do bikini shoots on a time for prints basis, which means they work for free, as long as they get a copy of the prints for their portfolio. So I take some free pictures (at best, at worst I rip them off of usenet or a web site) drop them into the "app" it took me a day to write, change the name, and submit each one as a new app? I must say I'm no prude. I've seen my share of porn, and I am neither shocked nor offended by anything you can get at the local news stand, but I quickly grew tired of going through page after page of bikini apps. It was the app store equivalent of spam. Did this happen the first time a wobble app or bikini app appeared? No. It happened after at least one dev took advantage of the system, submitting roughly the same app almost 500 times, categorizing it in multiple categories, and rating it much lower than the age it was actually appropriate for (13+ IMHO).
Playboy and Sports Illustrated are long established outside of the app store and can reasonably be expected to play by the rules, so they get to stay. I would be upset if I was the dev of iWobble... I empathize. But something tells me most of the squeaking we are hearing is from the people that were classifying the "same" bikini app in the travel section, utilities section, game section, etc, and now they've had their "spam" shut down.
The app store in general polices itself... bad apps get bad reviews. In fact, I read the reviews of bad apps to see what apps people use in lieu of them. Add most males over the age of 13 to the mix however, and boobs will rule the day, regardless of whether they are "spam" or not.
Just my $.02 (ok, it was more like $1.50)
