Here is a video showing what r_drawothermodels 2 does. Skins cannot cause r_drawothermodels to be set to 2. Only cheats/bypasses can.

p.s., sorry for the bump but I wanted to get this out here so people know really what he was banned for. r_drawothermodels 2 is a type of wallhack which allows you to see the wireframe of people and certain other objects through walls and stuff.
