I don't get why this is framed as "nowadays". Bad stuff happened all around millennials too. I can has cheeseburger and related sites were huge almost as soon as they launched in 2007. Then the same thing happened with much older generations as well - my parents and a lot of people from that generation repeated lines from old political comedy shows - basically memes before the internet. Kilroy was a WW2 meme.

It's more "the same thing that always happened happens now, just increased by the presence of the internet".
