If the current pin is correct on the map, trying to move the pin is considered abuse.
If the current pin is not correct, then you can ask help chat (Niantic Wayfarer) to correct it. They will want evidence of the correct position. You can submit geo tagged photos, photos that clearly document where the point of interest is in real life against items that do show on Maps for comparision, or even do “Splats” as explained in Leveling Up Your Appeals and Removal Reports to prove the real location. They will NOT do moves simply to put something in an empty L17 S2 cell so it will show in Pokemon Go.
