In the early 2000’s there was a porn site that completely covered you screen with porn pop-ups when you visited it. The funny joke back then was to opened it on school computer so that the poor teachers had to close them one by one (boot the PC if they were more savvy).
Today you can just open any major news site without ad blockers and effect is almost the same. There’s no porn, but it’s almost worst with the crap they open on your browser without asking. No wonder people rather get their news from social media.
GNAA Last Measure? It did a little bit more than just opening a bunch of windows and yelling "Hey everybody, I'm looking at gay porn" :)
