According to the out of date Intel Map there is at least 2 waypoints already in the same cell.
Information on Pokemon Go and S2 cells can be read here https://community.wayfarer.nianticlabs.com/t/why-an-accepted-wayspot-may-not-be-used-in-pokemon-go-s2-cells-and-pokemon-go
Your nomination may…
- become a Powerspot (Dynamax / Gigantamax) depending on its proximity to other waypoints.
- replace the existing waypoint if that is removed for legitimate reasons. ***
- be used in other Scopely games.
***Do Not attempt to get a legitimate wayspot removed just to get yours on to the map. This is seen as Abuse and can lead to suspension / bans of all accounts (Wayfarer, Pokemon Go and any other Scopely games).
