[GitHub Prohibits Registration of New Accounts Using Outlook and Hotmail Emails] According to a report by Jinse Finance on September 28, citing BlueDot Network, Microsoft's code hosting platform GitHub has quietly banned the use of Outlook and Hotmail emails for registering new accounts. Existing accounts are not affected, but new registrations using these domains will display a message stating 'Email cannot be verified.' GitHub explained that after discovering persistent and organized fraud and abuse associated with the Outlook and Hotmail domains, it has suspended registrations using these two email providers. Users are advised to switch to other supported email services, and GitHub will continue to evaluate measures to prevent abuse while ensuring secure access. The ban is attributed to black and gray market groups exploiting these high-reputation email domains for bulk registrations and abuse. There is currently no timeline for lifting the restriction.
