Since I was advised by the sloth to put it in the forum and I’m too lazy to type it out again, here you go. The idea is basically to have an easy way to determine whether a merchant/account is still active or abandoned (lost his keys, given up his business, on a break, etc). As a buyer you would not like to buy a “ghost-listing” (yes, I like that word) and never see your product. Looking forward to hear your opinions and discuss.
Edit: As an escrow provider later on, you can probably step in line, check the status of the merchant and send over funds only after successful checkup.
