It is impossible to find guys by ethnicities. This diminishes the access to minority customers. It has the opposite effect to that intended. Man up Grindr. Bbrt, PR, a4a, etc. have more thoughtful and logical policies. Add to that endless spam messages, intense back-to-back ads for obnoxious, useless things, along with a system where as soon as you delete a (spam) message you are forced to watch a full-screen, animated ad, then another. Delete next spam, repeat. Big fail for Grindr.
