IT guys have access to everything. <-- The single most misunderstood concept by management to this day.
IT guys typically are on the web all day *cough* and get exposed to a lot of stuff other people don't, like Epstein memes.
IT guys can also get bored, nosey, and so on. "Idle hands" and all that. I was never one to go snooping, but I used to work with a person who would read other people's emails. I did not know that until I had left that company or I would have reported it. (Justin at Boise. He was a slimy little tool.)
Even if you're not a snoop you can stumble upon things when doing official tasks. I stumbled upon a pay stub recently that really pissed me off. (Documented elsewhere) A co-worker stumbled upon a lesbian affair at OAPI when he was reviewing VMs after one of them was fired. (Although, I'm not sure he was supposed to do that?) And so on.
I was an IT guy at a news station and have a copy of something that aired the station tried to cover up. I might have the only copy in existence.
