Decided to just come out and ask since the search results aren't giving me much.
The free tiers on most of what I've tried are basically useless — you get just enough to see that real people are there, then hit a wall the second you try to actually message anyone.
The account verification process tells you everything. Platforms that skip it are the ones you'll regret spending time on.
Would really appreciate any honest takes from people who've actually tried different options.
