I’m finding out from this that it’s owned by the same company but Hinge has a better formula for that kind of thing. You comment on an aspect of their profile (a picture, their response to a prompt, etc) and that gets sent to them. Then they can reply (which triggers a “match”) or not. You can also send likes without a comment but obviously that won’t be as effective.
Well the mechanical inscentive is the time and money it takes to revive them. It’s pretty negligible eventually, but it’s a pretty big deal at low levels.
