  I am surprised that this blog post went through legal including this detail (https://archive.md/ZD1zc): In the next paragraph they write the fraud rate "on the order of 1 out of every 1,000 payments.", so their false positive rate is as high as the fraud rate.

  This is a horribly editorialised title. In my view (as a e-commerce store owner) a false positive rate detecting fraud across their whole network of only 0.1% is very very low. If I'm reading it right, that's 1 in 1k blocked transactions are incorrect, not 1 in 1k all transactions!

  > The challenge is compounded by the fact that fraud is rare—on the order of 1 out of every 1,000 payments.

  So 0.1% of 0.1% (0.001%) of transactions are incorrectly blocked.

  > Out of the billions of legitimate payments made on Stripe, Radar incorrectly blocks just 0.1%.

  Or rephrased:

  "Stripe wrongly blocked millions of payments." What a headline!

  Let's see which news outlet will use it.

  That is definitely not the title of the original article.
