Create some version of AOL Instant Messenger's old "Warn" feature for flakes/fake profiles
In addition to the usual spam/bot accounts, this app has way too many users who either have fake profiles or lead people on without ever intending to actually meet (presumably most of them are just pic collectors). I would wager that all of us have experienced this multiple times. Grindr and other apps need create a feature similar to the Warn button that AIM had in the early 00s.
Essentially, every user had a Warn meter that started at 0%. The feature was intended to alert others if a particular user was hostile, a scammer, or otherwise should be avoided. If someone hit the Warn button on your profile, the meter would go up a small amount, and then slowly decrease over time back to 0. If your meter got too high (because multiple other users Warned you), certain restrictions would kick in. First, the number and frequency of messages you could send would be limited and at a certain Warn level, your account would effectively be suspended for several days.
Obviously this feature would need some tweaking and updating to work for Grindr in the 2020s and to prevent it being abused by users. But it would ACTUALLY do something to eliminate bad faith actors and fake profiles on this site if a reputation for repeated bad behavior became attached to their profiles. Even if grindr doesn't want to use it to issue bans, it would at least allow the rest of us to avoid the guys who come here with bad intentions .
