I choose the sites like J4Luv which don't pay their women. It's not easy now to find such sites, but I know for sure at least the one I mentioned is credible.
You can't exchange contacts on QuickFlirt, all messages are monitored and modified. But even if you give them your contact details, QuickFlirt women won't contact you. They are just doing their job on the site, that's why they aren't interested in free means of communication. It goes without saying that they are not interested in meeting men.
These women are real but their motives are evil! They are there to scam the men.
