Is there a way to ban an avatar from purchasing items from your marketplace?
It's terrible when people abuse the review system and weaponize it to hinder your market potential, doubly so when you offer free demos and they still "buy" them only to review bomb it, LL is mostly useless when it comes to this, for example, someone writes a negative review because an item is no mod, even if the description specifically says the item is no modifiable, when flagged such a comment is still allowed to stay up.
LL has the foresight to disable the gift option from zero linden items, to prevent abuse on that regard, but they still leave the reviews on so individuals have nothing to lose.
Other than that, they can still use low cost items to make your life misery, and if anything the ToS specifically says you are not allowed to relist an item.
So I ask again, is there a way to flat out ban certain people from buying anything from your store, because having to deal with this kind of harassment is almost a full time job and the number one reason why almost no one has demos on their Marketplace or a Marketplace to begin with.
