To avoid finding out that someone has squatting on your desired username, an up and coming social media platform called Bluesky is implementing a simple solution: using your custom domain as your username. This approach eliminates the issue of identity and verification problems associated with traditional usernames. To achieve this, users need to update their Bluesky handle to leverage their custom domain with Netlify, which requires setting up DNS records and verifying them on the Bluesky platform. With these steps, users can now create branded Bluesky accounts without worrying about someone squatting their desired handle, allowing for a more secure online identity.
