Grindr needs a complete re-think.
It needs to start by avoiding fake profiles which is a plague. It will stop people being nasty and use the anonymity to do all sorts. If you can misbehave and restart whenever you want it is not really right!
Return to being a sex app and this where I am going.
You be able to have some sort of rating in your profile ( like airb&b for example)
Starting with honesty about the pictures
Following by the if you are seriously meeting people or just wasting time
How likely you are to meet
Link the profile to IMEI number of the phone ( as you know you guys can block someone using that phone to ever have another Grindr) so people can't endlessly create another profile. Let's be honest here is why would you keep doing this if you are honest and acting respecting Grindr community guidelines.
The ratings could be :
Genuine profile and pictures
Likely to meet
Of course this need to be in partial.
For example you choose to hook up, the profile deciding to travel receive the location where to meet up the other profile. When you are there you can verify with GPS that you have been to the meeting point and both profile can rate :
Yes I went and we have met
I went but no one was there
Yes the person looks like the pictures
The one accommodating can also vote the same but his voting is still validated by the GPS
Just going against those lines more or less
Please feel free to contact me if you want to discuss more as it is a little bit difficult to put the idea in writing.
