It doesn't matter if they know who did it or didn't do it - they aren't banning anyone because it doesn't even meet their own definition of an exploit. That is why they changed the functionality and referred to it directly as a functionality change and not an exploit fix. They want to sell raid bypass timers and they can't do that if people finish only parts 2 - 5. So now you must complete the parts in order, but it was never that way previously and the shortcut has been around for many years. Groups rarely did it because they wanted all the chests. In legacy people find part 1 so boring they are willing to lose those chests.
You are who you are and I doubt you will ever change.
I am not going to adjust my raiding due to Turbine bugs.
