While it’s very good to remove links, for cleaning up AcoustID database, MB recordings should still be auto-removed without unlocking, as long as they don’t have any MB relationships or releases, even if they still have some AcoustID links.
But maybe I’m wrong.
You are likely correct. I may be confused with when there is also a link to a work… I wiped them all out anyway as I can’t do half a job. 
Releases now gone. Thanks for the votes. Artists nearly all have gone into auto-self destruct.
Only one recording left due to it having a Work linked. Vote for its removal here: Edit #129420724 - MusicBrainz
Labels also gone into self destruct.
Can’t do anything about the artwork. Even if it had been marked to “delete” it would have stayed on CAA anyway. Unless someone knows how to submit a list of artwork to CAA for destruction? Something they must have an ability to do due to copyright?
Thanks all. Main task of clean-up is done. This batch of fakes are gone.
