The same problem exists, but has less of an impact on other platforms as well. For example, switching to a domain based handle on Bluesky will make your old handle available for re-registration. That makes you vulnerable to impersonation via the old handle.<p>I wonder if some of these platforms could allow aliases, so, using the example in the article, switching from 'MyOrganization' to 'NewOrganization' lets you keep 'MyOrganization' as a permanent alias. Obviously that would invite namespace squatting, but I think you could solve that by charging a one time fee for an alias. If you're renaming an organization it's likely worth $50+ to keep the old namespace.<p>Ideally, everything should move to domains as namespaces IMO. I'd rather maintain a single domain vs (hopefully) matching namespaces across a dozen different platforms.
