There could have been a problem with recently created accounts posting a few listings right away, posting a listing for an item which is similar to that item some fraudsters have been selling, or maybe their resident prophet read a sacrificial bull’s entrails and told to beware of the topic starter. You never know. And they won’t tell you. And this arbitrariness is the problem precisely. And no, an argument that telling the reason would help the crooks is not going to work, or the place wouldn’t be swarming with them already.
