Around 6 months ago I made a profile on Kippo, the 'gamer dating app'.
Because of the gaming centric focus, you either can't or have to pay money to filter by things that might actually make sense for a dating app (religion, political beliefs, do or do not want or have children etc)...
... But what everyone lists is their favorite games.
So I made some basic rules: Hard No for anyone who lists League or other games that are notorious for the extreme community toxicity.
... And LoL being a Nope filters out about 80% of people.
I no longer have a profile on Kippo.
