Which wayfarer criteria is this grounds for rejection? This is a swimming pool for a condominium.
The AI rejected it. Likely because the photo has too much water and sky so it could not recognize the area as a pool. Try another photo and if that fails then appeal it.
If its rejected by AI, you can either resubmit with better foto until it pass AI or appeal (you have 2 appeal , each with 15days cooldown)
I would just appeal, thats very annoying though!!
