Pero las celdas estan ocupadas, que hago?
Welcome to the forum @onirico777 !
If the pin locations are where the points of interest are in real life, then everything is correct and there is nothing to do. Not everything can be a Pokestop.
Welcome to the community.
Even if the cell is occupied with an existing wayspot, it shouldn’t deter you from submitting another one. In Pokemon Go, they may end up as a Power Spot, and if they meet the >20m rule, it will appear in Ingress. Also, if and when the other games sync with the database, it may end up appearing in those games too.
