It's strange that it is also calculated based on your removed "accepted" names (which have never been published), e.g. you got a domain accepted, disagreed with the pricing, and then removed it from your "to do" list.
Doesn't really make sense to penalize sellers for not moving forward with publishing an accepted name, since this usually happens because the seller disagrees with BBs suggested listing price. For a published name, they have created a description and a logo, so I do see how they consider this to be a "loss" on their part, even though they didn't do this for free, as there is a listing fee (and also, removing published names *could* mean that you are selling names to end users right after the end of the 30 day removal period, bypassing BB). However, for an accepted name, they have simply added a suggested price to it, so it's not like they expended a lot of resources on "accepting" it.
I've only removed a few published names, all because of underpricing or ugly logo, and the number is so small that it would not have any impact on my account score. However, I have removed a lot of "accepted" names from my to do list, as I decided to not move forward with publishing those names, usually because I disagreed with them on the price. With the introduction of the dashboard scores, my bottom right account score (removed accepted names) now means my account will never be in "good standing" with them. With this new change announced by Nat, they have effectively excluded me from the BB re-seller market. And apparently, they are going to introduce further penalties and "sanctions" against accounts that are not in good standing in the future (and benefits for those in good standing).
According to their dashboard, I have a 5.4%+ sell-through rate and am in the "top 6% of sellers" - yet my BB account will increasingly be limited and disadvantaged, because the only thing that matters for them is whether you publish all accepted names, and then keep them published in perpetuity.
