Depends on whether you installed arch on the plane yet.

And they’re all so pretty and cool.

And who should decide if it’s a political ad or not? You could count anything as political ad. Of course there are more obvious examples, like the logo of a political party. But there’s also symbols of political groups, like LGBTQ flags, free software mascots, free software license logos, the fuckcars banner, and whatnot. Your suggestion is just not feasible.

Or to make it more realistic, let it expand like the universe. I.e. add extra space between each two pixels:

w=blank/white, b=non-blank
wwwww
wbbbw
wbbww
wwwww
->
wwwwwwwwww
wwwwwwwwww
wwbwbwbwww
wwwwwwwwww
wwbwbwwwww
wwwwwwwwww
wwwwwwwwww
wwwwwwwwww

Or keep non-blank pixels together, because of pixel bounds.

Maybe also unsolicitedly notify any users who recently placed pixels in a radius around the message.
