So sorry you are feeling so down. Those other game locations you question could have been accepted in error, imports that never had to meet criteria just to seed the game so it could be played, or maybe there was a fantastic case made in the supporting statement that you don’t see as a player. Don’t just submit what you see in game without knowing why they are eligible, or something random where you think it would be great to have a Pokestop. You will have the most success if you can make a convincing statement that your nominations meet current criteria. Here is a handy reference: Wayspot Criteria — Wayfarer Help Center
