i have found a glitch where you can skip both the prep's and the setups meaning you only have to play the final heist. is this allowed and if it is should it be banned?

can show how its done.

i mean the heist it self not the final heist so like you still have to do all the heist

We have no category for just the final part of the heist. You must complete the heist from start to finish including all setups. If this skip allows you to start the setup and skip the the end inside the setup, sure. But a major glitch like that would be very likely to be patched. If you dont start the setups at all then the run doesnt count

can you show this glitch? sounds interesting

The glitch works like you hold space over a prep that is next to a setup. (buy prep bind) You let go of space and at the same time you press arrow to go to the setup, sometimes takes a couple of tries. It tricks the game into buying the setup.
