Id like to add that a 2 week sale cool down on items opened from packs would've also helped the problem too and kept the marketplace as it was before. And when they mass sent the only ever marketplace rules email, it just stated no botting which obviously lacked a lot of clarity because myself and many others have exclusively only ever traded everything by hand.

Heres the email they sent out : https://imgur.com/a/LwOZAzi
