How do people get all those LoL accounts?

[ItsLevi]

On a facebook page there is a guy selling LoL accounts with 400+ skins tons of RP and IP points 20 rune pages and on and on....Those accounts are worth over 2000$ , he sells them for about 200-500$ he has sold multiple ones , the accounts are real I've checked it and there are people who bought them.How does he find so many accounts that are like that?I really doubt he levels them all up goes to certain devisions , buy over 2500$ worth RP and more.

He probably buys and resells them

He buys them for what 30$ and then sells for 150$?
Where the hell does he find that

Probably phished or hacked accounts or something.
