League of Legends has a very unique account selling problem that Riot have proven outright fucking incompetent in addressing.
You need to hit level 30 on your account to start playing Ranked, which can take about 112 hours of cumulative play time to achieve. This has created a black market for fresh League accounts that have been pushed to Level 30 and are ready to be played in Ranked.
Unranked League accounts that are level 30 fetch about $1 - $10 on illicit websites because there are whole industries of Chinese gold farming firms and bots infiltrating the game. If you want an account that’s in Iron 3 or Iron 4 (the two lowest divisions in Ranked), it can fetch a few hundred dollars at bare minimum, at least if DongHuaP is to be believed. Iron accounts are so expensive because of how hard they are to actually get into Iron in the first place without tripping Riot’s automated reporting systems and getting banned, but also they’re lucrative for YouTube content creators because they use them to do ‘Iron to Grandmaster’ series.
I’m somebody who peaked at Archon rank in DOTA 2 (LoL equivalent would be Platinum) and used to play StarCraft II at Master level (second highest league in the game, Grandmaster is top-200 in the region), so I’m not exactly incompetent at RTS or MOBA games. But in League my account is borked and I’m in literal elo hell. I have found it impossible to climb above Iron 2 because of smurfs, bots and powerlevellers inting their accounts deliberately so that they can resell them.
