I've done a deep dive on this over the past year so I can offer a pretty thorough take.
Support quality varies massively. Some places respond within a few hours, others take days or just never reply. That alone tells you a lot about how seriously they take their users.
For what it's worth, datenest.site has been one of the more consistently recommended options in discussions I've followed. Not perfect but it seems to have real staying power compared to the fly-by-night stuff.
A few things that have genuinely helped me:
- Free trial is usually limited but still enough to judge real user quality
- Bots usually reveal themselves within the first exchange if you say something specific
- Location-based platforms tend to have better engagement than broad national ones
- Premium tiers are sometimes worth it — but only if the free version shows genuine activity
Anyway, hope that gives you something concrete to work with. Feel free to ask follow-up questions.
