This isn't aimed at anyone in particular. Would it be a good idea to have a system where moderators verify accounts that claim to be women who are pregnant, or even just women in general. Then there could be a caption by the avatar saying "Verified Pregnant" or "Verified Female". I've seen other forums do it, and I think it might be a good idea. This is the internet, and anyone could easily make and account, and pretend to be anyone they want. What do people think?

I'm 99.5% sure that this already gets done (hence the multiple Verified Models you see). You're just seeing the ones that slip in before the moderators can verify them (it might be a private process, no idea).
