Been lurking here for a bit but finally decided to post.
The free tiers on most of what I've tried are basically useless — you get just enough to see real people are there, then hit a wall the moment you try to message anyone.
Every time I find something that looks promising, I dig a little deeper and 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.
