I have never dealt with OnlyFans women but I have seen some ads on bedpage that only show an onlyfans website for contact. What kind of services and extras are offered?  Is it legit or is it pay with no play?

I’ve always assumed it’s just a ploy to get you to sign up for their OF but have met providers since that had OFs, so who knows.  

They now do this on just about all escort advertising sites, bc that's where the traffic is and guys do subscribe.  You will get online content only.  With OnlyFans and other sites like that, it's a violation of their TOS to solicit in person sex services.  Which means if you inquire on that site about seeing her in person, you and her run a huge risk of having your accounts being banned, could possibly lose the money you paid to subscribe.  So I doubt she's using OF to openly advertise for in person services, unless she's that reckless or running a scam.

Like Ms Quinn explained above, OF models don’t use that site for solicitation. The Tryst ads you’re looking at are just advertisements for her website.

On an escort ad listing site.  Some of use the BP replacements or other sites such as tryst.

For fun, I tried this with two gals who claimed they were in the NoVa area. Could never arrange a date, they just wanted me to pay for a photo or video before we could discuss. Paid for a video (in one case, pretty good), and then she'd say, please buy another before we can talk. As noted by someone else, OF gals are not supposed to use the site to set up dates for sex. (I have been with many escorts who have OF sites and they try hard not to cross that line on the site.) So if you see an ad on an escort site with an OF address, keep scrolling.
