I'm using using a Revanced patched version of RIF is Fun to access Reddit. I have a VPN with ad blockers running. The app doesn't have location permissions. I am getting ads for my city in it. The odd thing is that before the banning of 3rd party Reddit apps, I never got ads on RIF. I'm not only curious how they're finding my location, but if anyone is getting paid for these ads since RIF has officially shut down and it's only usable because of the Revanced patch.
Or poison the well. Leave your city sub and join a few different ones. Add and participate in several subs that don’t actually pertain to you.
