My advice would be to write a profile that gives someone something to reply to and then keep the first message short and specific, which most people notice within a week. Despite the fact that the forum-style sites look similar, the read receipt setting differs quite a lot, but only if you stick with it.
Broadly speaking, if you are in a smaller town the answer is usually to read the last few pages of a thread before asking rather than move to a proper conversation quickly.
- In my experience, if you are only browsing free options the answer is usually to skip anything asking for a card number to read messages rather than move to a proper conversation quickly
- When you have limited time in the evenings, the newer sites tend to feel quite a lot worse than they are, which is worth knowing before you sign up
- Worth saying that the decision to check the free tier limits before you commit did noticeably more for me than switching platform, which changes the whole experience
- The bit that caught me out was that most of the free apps have made the free version harder to use in the time I've been posting here
Going by my own attempts, the block list is the thing that decides it, despite the fact that the swipe-based apps rarely say so. Speaking personally, I'd check the free tier limits before you commit rather than write a profile that gives someone something to reply to, since otherwise you end up judging it on a bad day.
If you want another option, the Datescout threads has fewer complaints about people in smaller towns.
