Blur @blur_io, NFT marketplace backed by @Paradigm on Twitter:

"We originally considered the bid mistake to be a user error because there was no bug in the product per se. After evaluating further, we see how this can be considered a bug from the user’s perspective, so we will refund 50% to traders who were affected by this UI behavior.

Specifically, we will query for collection bids that were accepted over 25% of the non-flagged floor and refund them automatically. We'll do this within the next 10 days (likely sooner).

For completeness, our explicit policy is that we'll try to refund users for platform bugs. For user errors, we'll improve the UI to reduce errors but not issue refunds. If an issue seems to be a mix of a bug and a user error, we will adopt a middle ground on a case-by-case basis."
