I would like the opportunity to sign up for an optional reliability score.

It could work as follows:

Create a button in chat by pressing + that says “agreed to meet”. It should then send a message to the other user that says “agree to meet?. To confirm they are both in agreement.

When Grindr detects both users within a few feet, a pop up could appear that says “it’s looks like you have connected?”
If both parties agree, it will give each a point for reliability.

There could also be several additional options…from chat hitting the + button gives options for “sorry I need to cancel”. Cancelling will lower their reliability score, but not nearly as much if there was an option for “ghosted” which would hurt the score more.

People who have a low reliability score should be moved to a low position on the grid for 30 days and the score should be permanent.
