There is plenty of evidence, look at the lives of nearly anyone who has been suspected of online piracy. You're going to see a very strange pattern where something catastrophic happens to them and their lives fall apart in a nearly impossible series of events. I personally know dozens of people this has happened to, there was an entire floor of RIT engineering students who were running piracy servers out of their dorm in the late 90s and had their lives torn apart with psychological operations. I tracked all of them over the past 20 years and it becomes deadly obvious this happens all the time if you start paying attention to anyone who was involved in online piracy or was friends with anyone in online piracy.

In particular, take a look at anyone connected to Efnet and Freenode IRC networks.
