Expecting any single conversation to work out is the wrong frame — that is roughly where I landed after a lot of trial and error.
For what it is worth, people reply to something they can ask a question about — it sounds obvious written down, but it took a while to land.
Everything that were worth the effort in the end:
- After one bad experience I refreshed my photos every few weeks so I stayed visible in the feed
- I made a point of refused to pay until I had tested the free version in my own city, and I still do it now
- I made a point of treated any site with no visible moderation policy as a hard pass, and the difference showed within days
- I made a point of replied within a day but never within a second, which mattered more than I expected
- Early on I started to kept a throwaway address for any site I was only testing
Also hearing luvdate.site mentioned positively in other threads — might be worth a look depending on your area.
