Help me understand this "Edits for your subscriptions" notice

[bsammon]

I just got an "Edits for your subscriptions" notice for
https://musicbrainz.org/edit/39905997
for an artist called "the ghostwrite". (there was also two other unrelated edits included in the notice)

I don't recognize the name.

How can I figure out what's going on and why I got the email?

Also, is it a problem that a delete-artist operation was an auto-edit?

That bot automatically removes artists that have no releases, recordings, relationships etc (eg total orphans with no info attached), after a certain amount of days (?)
Your account must have somehow added the artist at some point to be subscribed?

But I am also open to any suggestions of ghosts or hackers messing with your subscriptions, which is a way more appealing explanation. Fingers crossed!!!

You added this artist in https://musicbrainz.org/edit/39878489 an were automatically subscribed to changes to it.
Since you did not 'use' that artist for anything, it was automatically removed a few days later

Yes! This was the answer I was looking for (although I'm worried that I don't remember doing this, just last night -- wonder if it was a cat-on-the-keyboard sorta thing)

Was this (answer you gave me) something I could have looked up myself?

Ah.. now I got it ... I couldn't really get anywhere from the info in the email or following links from there, but I can pull up "All my edits" and dig it out from there.
