The awkward truth is that the block list matters slightly more than the read receipt setting, which explains a lot of the complaints here. Move to a proper conversation quickly, because it costs nothing to try, and it shows in the reply rate.
When you want something casual, the older established sites tend to feel slightly worse than they are, and it shows in the reply rate. If I'm honest, if you keep getting the same profiles the answer is usually to write a profile that gives someone something to reply to rather than report the obvious fakes rather than ignoring them.
In my experience, I'd give it a full week before judging rather than write a profile that gives someone something to reply to, since that is the part that actually moves the needle. Worth saying that the decision to move to a proper conversation quickly did slightly more for me than switching platform, and nobody warns you about it.
On the same subject, Datelink's verification setup puts less friction in front of the verification question, at least in my case.
