No I've asked different question, that is not the answer to this question. directing me a third party is not the correct answer. Maybe I should why this has never been implemented over the years is this a policy issue?  There is not technical issues to why its never been done. But you don't have the answer and could have said you don't know.

Your directing me to use another website? I'm sure the 'team' love that. Thanks

What really? why does it only half work? I should be able to block bad sellers
