I ussually go trolling when i don't like something but right now I am trying to make a valid point and what does getting paid for making a mod have to do with this there are a lot of Custom maps that don't care if you cheat they just make the map for as you say "for the love of modding the game"
because if we're not getting paid, then why would we spent months and months preparing a map when once it's released it will just get raped with cheats? it is pointless, and it ruins the gameplay and flow of the map. all the hard work getting the map to be challenging and unique is now thrown away. you, afaik, are not a mapper so you really would not understand this.
those maps that don't have cheat protection, i can guarentee you that either the map maker didn't know how and/or have time to implement cheat protection, or the map is old enough that cheat protection script wasn't discovered yet.
either way, those mappers wouldn't want you cheating on their map.
P.S if you usually go trolling when you don't like something, go ahead and try it out here on ZM, see where you end up
