Not especially Wayfarer, but how do we report fake photospheres?

Title says it all. The problem is, when I report the fake photosphere to Google, they spit error404. It worked in the past when I first dealt with fake poke stops, now I have no idea how to remove them.

Same problem I encountered, 404 when submitting the report to Google on desktop browser. However, I just tried reporting it on Google Maps on Android, and it works (at least it shows a "Thank you for your feedback" message)
I'll try the android today
