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.
I sorta loaded this picture in my brain like pictures used to load on slow internet - from the top down. So I saw the arms and the small face and thought it was one sloth looking through its back legs as it hung. So then I continued to load the rest of the picture and when I saw the big face, I tried to make that fit with my earlier interpretation so, for half a second, I thought that sloth had a face for an asshole
