We’d also like to address the claim of a “leaked” list of Coinbase emails and user names. This list (the size of which is less than one half of one percent of Coinbase users) was not the result of a data breach at Coinbase. This list of emails was likely sourced from other sites - probably Bitcoin related ones. It’s clear there was no data breach because no other user information is provided. That last sentence is doing a lot of lifting, out of its weight class. This immediate "no it's not true" might reassure some folks, but it scares me because of how quick it is. Have you looked at the audit systems on your database? "We believe this information is bogus but are investigating to make sure" is a better response, assuming you actually do investigate to make sure.
