These all refer to the main developer of pixelfed, dansup. The first one is dansup's pixelfed account followed on slrpnk.net where my account is. The second one is dansup's pixelfed account followed on lemmy.world, the biggest lemmy instance. The third one is dansup's pixelfed account followed on lemmy.today, which is your instance.

The account is visible to me on the first two links. HYPOTHESIS: I think that means it's "being followed" by those instances? The account is NOT visible on the last link for me, I just get an error. NeatoBuilds, take a look at the last link: it might give you an error the first time, but HYPOTHESIS: if you refresh, I think it will be visible and that means it's "being followed" on your instance lemmy.today.

search @username@pixelfed.social and you should see the user pop up.

@user@server.url just like any other account. It should show up. Another option is to search for the post on the top of lemmy and then navigate to their account.

Example: @dansup@pixelfed.social

If that doesnt work, you can try this: https://lemmy.world/u/@dansup@pixelfed.social

in other words your telling lemmy to go to his personal account, which happens to be on another server.
