Easiest way to get to the deep web and how do I find decent shit on there?
You know a guy or you don't.
If you don't, you consult the wiki and maybe look into communities who will PM you the addresses and subdomains willingly. This will probably fail if you don't know what you're doing.
A lot of it is hush-hush enough that less than maybe a few dozen or the count on a single hand would have business knowing. It's called the deep web for a reason, not the hipster web.
What the fuck are you looking for anyway?
OP is a pedophile
Also everything you likely hear about the deep web comes from faggots on reddit who post made up shitty stories about it.
If you want to waste your time on slow to load scam websites then feel free to use tails on a live usb.
You could probably look up the hidden wiki and go from there.
If you seriously just google "how do I buy drugs online" one of the first links will be a comprehensive walkthrough for you to follow, including all links. There's even a subreddit for people who think it's too hard and spooky to go through the process alone
