In the brief time I was single I did get on them but I quickly took them down because I knew a fair amount of people that use tinder, specifically, and didn't want any of them to find me on there.
This is anecdotal, but I can say this - I met a girl on SA that started off hating me, but I killed her with kindness and literally got to fuck her off of that and dinner. I did give her some money because she needed help with rent, but it was after I had already made a video dropping a load on her stomach and face because I felt bad she was about to get kicked out. I spoke to her a while back and she said she quit SA because people were too creepy on there, and in the following ~2 years slept with over 100 guys on tinder, almost all raw and even let them all drop loads in her while she wasn't on bc. I'm sure they're not all over the place, but I'm also sure with a good/funny profile to get the proper direction swipe and guessing the right way to butter up the girl it's still doable.
Plus, like David Spade said there are probably a lot of hybrid hookers - they won't take money, but they'll hit you up for a washing machine later.
