Welcome to the forum!
Campfire takes a while to update, so it is not a good indicator of current Wayspots.
From what I see on Street View, my guess would be that this was removed as SFPRP (single family private residential property) even though you say it is not:
If you have evidence that this is not on the boundary fence for that type of property, you should present it to help your case.
The other reason I could guess for removal is a property owner request.
For the record, I have no say in the outcome of the appeal. I am just trying to help.
