Clean Slate Glitch?

Then again, when was Orbis PQ declared a glitch?

Yes, OPQ was declared a glitch. I forgot how long ago and I'm not going to search for it but I do remember GMs saying that if they glitch the PQ and are caught, they will be permabanned.

And yet people were blatantly spamming 'J>GLITCH@@@@@'
They even admitted to it.

Yes, they did. That's because the rule was not enforced. Notice the lack of GMs.
