I'm here since 10 years and I really find it wrong that a newcomer has 3
NPB as much as someone who is here since years.
I'll explain you why.
I really believe that a newcomer with 0 to 9 feedbacks shouldn't be allowed
to have more than 1 NPB chance. If you miss that, you're out.
As a seller, I have been targeted too much with newcomers that realize they don't
want to buy after the order was placed. This means my bricks are blocked for
7 to 21 days.
If I do cancel the order, the buyer can give me a negative, so I have to undergo
the NPB procedure in order to prevent the seller from giving nasty feedbacks.
I believe that sellers may be targeted with NSS for facticious reasons, like
"1 piece wasn't in the package, I start a NSS" from a 0 fb rookie who still
doesn't know how BL works. Sometimes BL takes a lot of time to reply and
this lead in the past in the closing of many shops for a third NSS which wasn't
actually real. Giving a 4th or 5th NSS chance it's just a compensation for
possible "fake NSSs".
I'd personally prevent 0-9 feedback rating users from leaving negative feedbacks
too. But that's another story.
