Welcome to the forum @Julian880077 !
Are you trying to appeal a rejected nomination? You do that through your contributions page. You get two appeals, each on a 15 day timer before you can use them again. If you don’t see the Appeal button, then you don’t currently have one to use.
I do not believe this sign meets any of the criteria of a great place to exercise, explore, or be social: Niantic Wayfarer
I know that the prompt tells you that you are submitting a “Pokestop” but you are actually submitting a Wayspot that may or may not be used in Pokemon Go. The supporting section should not say why this would be good for the game, but help convince that it is a place that meets acceptance criteria I stated above. And any instructions the reviewer may need to help verify the place exists where you say it does and is what you say it is.
When you post here, it is more helpful for us to give advice if you can give us screenshots from your contributions page showing the rejection reasons: Niantic Wayfarer
We would love to help you be successful in adding locations to your community.
