Yeah I've spent years on the deep web; it isn't that great. It's mostly just cracked PayPals, credit cards, drugs, guns and lots of CP. The only 'scary' shit I saw was this live snuff film room once. There was a guy who was instructing this guy to do something to this bound up girl, and the guy gouged the girl's eye out. Don't know whether it was actually live or not, but eh.
Don't go on the deep web unless you know exactly what it's doing, not because it's unsafe or scary, but because it's just plain boring
