Could be. The final Ritual is by far the most damaging thing we have done as a group to the entire enemy agenda, literally disarming them of the energy mass they have been accumulating over centuries. I myself remember being targeted quite a few times, mostly around the time before doing the Ritual itself to try to deter me from it. That alone speaks how much it affects them, otherwise they wouldn't bother. I still remember HP Pythia mentioning at the beginning of the entire Ritual undertaking, that the enemy spirits tried to beg and bribe her so that she would not go through with that project.
