So I've spent quite some time on this now and I am impressed.
You need to read the OF pages to see if thwyre just contents creators or if they offer any adult services.
Most of the ones who offers hook ups have an AW page but this way you get to see their faces on OF if the AW page is censored.
There are also a lot of SP which doesn't have AW page and there's no way reviews to go on so this is the risk.
Finally I'm not interested in signing up to any of the OF pages so the only way to contact them is to see if they have an IG, Twitter or Reddit account and PM that way.
