was reading amazon seller forum, and to be fair - posts started appearing about 3 months ago when sellers were reporting that they were unable to apply to sell Lego:

And here
So seems like those were early signs of Lego becoming hard gated.
Then 2 months ago first reports started to come about sellers, who already were selling, having had their ASINs deactivated/gated
So it is possible that Lego started to apply similar way of policing its brand - like Adidas or Hugo Boss - when you need to be on brand's "white list" to keep selling, rather than simply being ungated (for Adidas in UK for example, Adidas "ungates" you by sending your info to Amazon).
Question is, how do you appear on their "white list"? I think it's similar in US - in UK there are almost no LEGO brand distributors. I only found two.
One is toymasters - who is the biggest PITA on amazon, they always sell ALL retired sets and will undercut anyone on price. They have endless stock. They said they would only accept me as their customer if I have a b&m store. Thanks but no thanks.
Another one was AIS - with my 6 figures annual turnover I was too small for them.
And even these above guys, they may themselves have authorisation, but can they pass on that authorisation to their clients? Depending if Lego allows them to.
Really hoping for some reversal of this stupid amazon action, but from reading forums seems unlikely...
