Going to a profile not your own (e.g., in the example below, that of Gustav Landauer Library Witten) will give you a tab for “External Services”.

I don’t know if this is supposed to show external services a given account is connected to (I would think not? Or do I have some super privileges still on BB that would theoretically give me access to that?), but either way, what it currently does is take me to my own “External Services” setting, completely unrelated to the editor I’m currently looking at. So either there’s a bug that it’s shown at all (which is what I’d guess) or there’s a bug that it’s showing my own external services rather than the profile being looked at.
