Coil has accidentally exposed some of its users’ email addresses in a mass email announcement sent out today. Coil is a micropayments platform that is used by writers and popular blogging sites to monetize content. The mishap happened within an email announcement related to the company’s Privacy Policy updates. The company was quick to spot the data leak and pinned it on a human error in a follow-up email. At least 1,000 emails were included in the announcement, and it is likely other users saw a different set of email addresses listed.
