I haven't explored the darknet in over 5 years, but some of these prices seem a bit high. Around 2014-2015 I saw PayPal accounts listed for $3 a piece ($5 if you bundled it with SOCKS proxy access). Which could mean a couple things: PayPal security has gotten tighter, restricting the supply of accounts; PayPal security has actually gotten worse, increasing the actual value of the accounts; or maybe these guys are doing "market" research and determined that their profit margins were higher charging $25 for the same product. It could also mean that the writers of this article didn't do enough digging to find a "better" deal. Interesting read but I'm not sure how much I trust their numbers
