'If you would like to appeal this account closure, we would be willing to accept an essay on ‘Why the use of third party cheat software is detrimental to an online game community' for our management team to review,' an email from Bethesda reads (via ResetEra). That said, Bethesda has allowed users of Fallout 76 graphics mods back into the game only if they write an essay explaining why third-party apps for cheating is bad. This is because, according to the emails sent by Bethesda, it detects any Fallout 76 visual mod to be a 'third-party application, which provides an unfair in-game advantage, while logged onto Fallout 76.' It appears that Fallout 76's monitoring tech can't tell the difference between mods that exist to enhance what is an exceptionally buggy game or those that straight up allow for cheating.
Multiple users have received emails from the company stating they have violated Fallout 76's code of conduct and terms of service by 'cheating'.
Bethesda has banned Fallout 76 players from using mods to improve the game's graphics.
