I'd say that's offensive against us unphotogenic introverted socially anxious geeks, but yeah that seems to be roughly how it works. Apparently one of my problems with online dating is not having enough pictures.
WRT profiles selling nudes/whatever, while I've never come across it myself (see: not enough pictures on my profile), the only problem I have is not being up front about such things. If you're only interested in selling stuff let people know so if they aren't interested they won't waste your time.
