Your article was uncurated because you didn’t include a statement on affiliate links or a statement that you are not affiliated with those products or services.

I have been uncurated over at least 6 times and I didn’t break any Medium rules in those articles that I am aware of.

Either way, Medium owes you nothing. And you should be thankful you made any money off that piece. I am surprised it got through curation in the first place given that it is a clear violation.
