lol those textures are the same as the covering fence of tzsux (s96 in your language) loc, there's no advantage, kyle had the option to shoot us back but instead he reported.
doing this is allowed everywhere else (on any server, you can check or ask admins)
there is no such thing as " wall glitch" there
the texture is solid only for keeping a player, for gun shots it's like it's not even there, you can't punish people for shooting through these walls - it is nothing
it is different than car glitch, the car has a different alpha than this kind of textures.
these kind of textures are made by Rockstar only for preventing the player to get through them, they were too lazy to make them resist to gunshots because everywhere you encounter these textures in normal Vice City you don't see any people and people would not notice this.
