Would love this idea, I suggested this earlier on this month I agree with you, this would be an amazing addition to the PokeFind server, like I mentioned in my post it would be cool if they had ranks (Example. A = Weedle) great suggestion
Pokemon prison = another short lived game mode. New Pokemon game modes have not taken off that well recently. Even pokewars is almost dead at times
As much as I would love to see the best game mode ever on the Pokefind server. But don't think they will add it since everyone just comes on to play on Pokeworld. But still will be awesome if they made a prison server. Pokeworld is kinda going downhill in my opinion. Since they stopped focusing on the Pokemon Go side of things. I think they can make prisons work if they don't rush making the game mode.. Like the last two, they added.
