My wayspot was accepted 1month ago and still not appear ..
Name of the pokestop : Suds Aquaticus - Fresque Codex Urbanus
Since this appears to be graffiti that should not have been accepted, it may have been removed. Have you looked on the Wayfarer map https://wayfarer.scopely.com/new/mapview to confirm it exists at all? If it does, if you give us the gps coordinates, we may be able to explain why it is not a Pokestop.
(I do see this is a recognized artist: Codex Urbanus - Wikipedia)
