I personally do not sell anything without being 100% in control of what happens to the money I receive when selling modules, or anything online. There have been far too many instances, not just on MG, but worldwide, of people abusing the buyers protection system. There is a reason why sellers on Reverb only sell items "as is". If they don't, they risk having the money they received refunded to the buyer, and they will never ever see the item they sent them back.
Who in their right mind would agree on selling something to a stranger with the condition that if the person you sold it to can simply revert the transaction with very little effort, WITHIN 180 DAYS? That makes no sense to me.
I know we have recently had a few cases of a user having their account hacked and buyers getting scammed out of their money. However the only two things that really allowed for that to happen were 1; bad account security by the user and 2; bad account security practises by MG.
It is beyond me why we do not yet have 2FA implemented on MG. A marketplace with this many users really needs more security features to keep their users' accounts safe, because it is common knowledge that the majority of people have a very poor sense of what makes for good account security.
