Fake accounts, no real way to filter, there are about 4 different "upgrades" for your account, so changing your location requires one buying one, seeing who liked you would then require buying a second "upgrade" and threwe have no set price, tinder charges you an amount based on your location, age and ethnicity and the price gouging is disgusting, £30 per month the bottom tier "upgrade" whose only feature is to see who liked you. It's nothing short of fraud to be honest
