Well, that took a while :)

It'd be great if some of the excellent points above were discussed a but more widely.  Perhaps https://community.openstreetmap.org/c/help-and-support/tagging/71 might be a suitable place?

Also, I'm sure that there's some "low hanging fruit" among the reverted data that "obviously isn't any sort of reservoir".  I've done a couple of the more obvious ones from earlier in the series of series of reverts, but the 394 nodes (including at least one mobile phone shop!_ on https://www.openstreetmap.org/changeset/136672560 are surely worth a look.

PS:  Other reverts of changes by this user are still ongoing (currently https://www.openstreetmap.org/changeset/136671982 - there will likely be a couple more in that series too), as we have had what might be a record number of separate individual complaints about their edits.
