Recently, we’ve been made aware that a number of you have had an influx of GitHub emails from a fork of Unreal Engine that you’re watching due to the fork owner granting the organization write access.
To prevent receiving further updates on the repo, click the little Bell icon by your profile pic, choose the Watching tab and select “Unwatch” on the repos you wish to no longer receive notifications from.
To avoid this in the future, head to your GitHub account settings, select "Notifications, and uncheck the “Automatically watch repositories” option:
In the short term, you can also filter messages from [EMAIL=“firstname.lastname@example.org”]email@example.com in your email client to avoid the current clutter. You’ll want to revert that filter once you’ve made the above edits so you’ll still receive notifications on repos you do want them from.
If you have any questions, let me know!
