Alright let's work first on cleaning it as I can see you're using pData[playerid][PrivateSkin] = 0; in many conditions while you can use them in one.
Also cleaning a little with else conditions.

+ I've noticed you're using if(pData[playerid][Admin] < 5) for clan owners, maybe you wanna revise that.
