They definitley could of added some code to make it impossible to do the glitch while podding in. Whether it's eliminating the use of the mouse for the time while your in air or something less drastic, something can be done. The only problem with the first thing I mentioned is some people like to look from side to side to see what they are landing in.

Just make the roof an off limits zone. Its like an out-of-bounds area. 15 seconds on it or your dead.
