Warning Flags for Fake Profiles
Users should have the option to flag a profile as being a fake profile (either spammer, scammer or the type that send pics, arranges to meet and then blocks you last minute),
To combat the risk of malicious or unjust flags, a system should be implemented where X amount of separate flags over X amount of time would be needed to trigger an active flag.
The flagged profile could feature a disclaimer saying something like 'Warning, multiple users have flagged this profile as being suspicious (Fake, Scammer, Spammer).' as either a 'first base' before receiving enough flags to qualify for review by grindr support team, or as a placeholder to warn other users until grindr support team have time to investigate.
New profiles could have a lower threshold of reports before displaying the 'Flagged' badge and/or before reaching the threshold of requiring a review from Support.
This idea has come to me as a few times recently I've got talking to catfish profiles that I'm sure I recognise, but I'm not 100%, then the inevitable happens and after hours of wasted conversation, usually minutes before they (or you) are due to arrive at the door a block is received. Then I remember this is where I recognise them from.
A quick check with local friends will confirm that the same/similar has happened to them yet these profiles remain live for days or sometimes weeks before being banned (or before the catfishes get bored or run out of people to deceive).
