Thanks for the appeal, @nexushoratio. We took another look at the Wayspot in question and decided that it does not meet our criteria for removal at this time.
But, if I proven that a portal was purposefully misrepresented as being permanent, and is indeed temporary, then leaving it sends a strong signal that particular criteria in unimportant.
So, whether Niantic means for it to be, it certainly acts like a criteria clarification.
As seen from the rejection email, (maybe only obvious to Niantic employees?), that came from reporting abuse, where they, for some reason I do not understand, redirected me here.
So, this is not an appeal about a removal, but an appeal about abuse. Making it about acceptance criteria.
