Come on guys, siege is a gameplay that strictly relies on these certain "glitches." What about putting a tele in super conts, making the supplier so you can use it on the other side of wall, making a tele through a wall to go to a secret room; the list goes on with these supposed "glitches." Multigunning is one thing, because it cannot be preventable and it is noobish to a certain extent when used 24/7 on players, BUT THIS IS NOT MULTIGUNNING. Bouncing requires a lot of skill and effort put to practicing it and this skill is what enables siege to run well.
Remove these and congratz, you have successfully killed siege.
