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.
Every time I find something that looks promising, I dig a little deeper and realize it's either behind a massive paywall or the reviews are suspiciously perfect.
If you've got experience with any platforms or approaches that work, drop them below.
