There is no object to place nudism= key on. No sign, no available boundaries. No fixed position. The next year this event could take place 500 m to the east or west.
Another problem is legality. You can't expose yourself in public places in Poland unless it is place designated for it. 
Mapping this doesn't make sense - anybody coming there and seeing no sign and no nudists have a right to delete whatever would be there mapped with nudism key.
