QuoteI have actually seriously considered setting one up under a subdomain on my site but I worry that moderating it would be a chore. There is one that I was a member of for a few weeks but its over run by mostly people with fetishes looking for sex or wanting to play dress up and pose for the camera in their underwear.
Yup you're absolutely right - the hosting isn't the problem (I have my own tier-1 facilities from some hosting business of my own), it's the screening and moderation. I wonder what methods we could think of that would be sufficiently effective?
I'd like it to be a free service, but requiring a $0.01 payment via a credit card prior to logging/responding is one way to verify identity and try to deter some those who aren't serious - of course this can deter legitimate users too and anyone who would be distrustful of revealing their card/identity no matter what security precautions were in place.
A lighter weight but unreliable method would be to require ISP based email addresses that can be tied to a person (i.e. no hotmail, gmail, etc.). It's always going to be a tradeoff between useability and reassurance/security.
I don't think any of these would lessen the moderation overhead - although this assumes such a site would attract enough attention in the first place
