Remember that not all accepted nominations will appear in all Niantic games (and may take up to 48 hours to appear).
Despite the language used by the game you are not submitting a new PokéStop/Portal but a new Wayspot which may become a Portal/PokéStop if it meets inclusion rules for those games.
If it has been a month, it seems it did not meet the inclusion rules for the game you have looked at, but has been accepted in to the database for other games to use.
Others have said what is likely to have happened. If you would like us to check and give a specific answer then we will need - the title of the wayspots and the exact location - coordinates are good and/or exact address.

They probably did not meet the inclusion rules for pokemon. Only one pokestop per cell.
