Posting about your intended crimes on social media is definitely the right first step.

I think the fact that a flyer's designs are AI generated already made them vandalized. Everyone knows and see through it.

They are messages and politician that hides their fascists/nazi inclinations so I see the point of griming them or explicit what they're stand for. I don't think it is necessary here, like the tesla nazi cars, everyone already knows.

The best would be to have human-made flyer next to it advocating for the opposite, I see more and more "human-made" logos lately.
