What MatthewG described matches my experience of 100 free christian dating sites almost exactly.
Before committing time to 100 free christian dating sites, work out what protection exists before you meet.
Gave it a fair run over 6 weeks and kept coming back to whether 'free' means free to browse or free to talk.
Unless you are in a major metro, expect whether the free version is a demo or a product to be the limiting factor on the platform.
