I was once involved with a non-profit group that was getting tons of internet trafficking attacking it. There were some 200 websites dedicated to this. After some investigation we discovered that all 200 sites were set up by 3 separate guys who were inventing phony identities. One of them was a homeless nut using a public library computer. And this was back in the early 2000s. It’s worse now with all the phony bot traffic.
