Short version: I want to understand safest way to meet singles for free without giving out your phone number before I put any more time into it. I'd happily ignore everything except hidden costs.
I would rate the options here average overall and poor specifically on hidden upgrade prompts. What people miss about phone number is that how bad the upsell gets scales with the size of your city. My goal is messages that land, so anything that gets in the way of that is a problem.
Still open to being talked out of my position on safest way to meet singles for free without giving out your phone number.
