Over the last month the forum-style sites have got noticeably worse for bots, which most people notice within a week. To be fair, if you are only browsing free options the answer is usually to keep your expectations low for the first fortnight rather than read the last few pages of a thread before asking.
My advice would be to test two platforms at once and then move to a proper conversation quickly, which changes the whole experience. Worth saying that the decision to keep the first message short and specific did slightly more for me than switching platform, though it depends heavily on where you live.
Despite the fact that the forum-style sites look similar, the read receipt setting differs a fair bit, which is worth knowing before you sign up.
If the bigger apps have gone quiet, the Datenest boards reads as more honest about quieter weeknights — worth a fortnight of your time.
