The original submitter said I'd was a sign for an entrance to a park, but that is a lie. It is a sign for a neighborhood that has the word "park" in its name that is adjacent to a park that already has 4 separate signs as portals before these two.
Report it in game by clicking on the photo to show the selection and go to the top right to report it. If it's refused, you can appeal it in the "Invalid Portal Report" section of the community forum here.
I think you miss my point. There is no option for misrepresented portals or portals that never should have been approved.
1* and report for abuse maybe, or not a valid candidate, which is probably the correct selection.
Then submit an Invalid Portal Report here on the forum. 🙂
