Nullified data on Kindle editions

[Lisa]

Does anyone know what the story is behind these Kindle editions for which the fields have all been edited to NULL? The information seems to have been deleted systematically by Otis Chandler but there is no note explaining why. There seems to be quite a large number of them.
Example: https://www.goodreads.com/book/edits/...

It wasn't actually Otis, but an automated Goodreads bot running under his profile. (This was before we created better ways of running such automated programs.) You'll note that such edits all date to the last few days of January 2012, when Goodreads was required to remove all Amazon data. But we're allowed to use Amazon data these days, so if you find any of these unreverted, it's fine to revert them.

I got that one.

Gotcha. Thanks!
