I see no problem with spawnwalking as long as where the person goes is actually possible for someone to be spawned there by the game and they have coords on. When I get back home I'll (hopefully not forgot and actually do) make a list of coords of the front spawns that people can spawnwalk to. If anyone seems to be off they'll be penalized by what the mod sees fit.

UPDATE: I FORGOT TO EMPHASIS THE PART THAT YOU NEED COORDS
