That’s how scammer scammed me on #bluesky :

Users on bluesky can impersonate user name and avatar of other users: previously, but after impersonating Dvorak, that user had user name @ tara… and now the same user has user name @ stel… , go to https://bsky.app/profile/comicstrip.bsky.social/post/3ldgd463j5s2k and click on @ tara… and you will see it switches to @ stel… .

So bluesky security is very broken.
