I wonder if the puppeteer vandalism (which also still remains on IMDb) is related to the animation vandalism: https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/incorrectly-credited-and-credited-and-credited/62eeb6da27c9e55d81c8f672?commentId=6309ccdcc5eeb86e2c3aecba

Other recent vandalism involving voice acting on animated films, discussed in a now-deleted Sprinklr post:

Fake Credits - Please Help

Another thread: https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/nearly-100-fake-credits-added-to-page/6309954b72837f15dbbe2f7f?commentId=630d08f172837f15dbbec133

@tormented 's reply there has good info. Like he stated there and I did in one of previous threads, "Jack Angel" is one of many names this vandal is obsessed with. These persistent vandals often do not only vandalize IMDb, they are often active on Wikipedia too. For example, if you check the history of Jack Angel's wikipedia page here, you can see they protected the page several times for "Persistent vandalism"

Following these crumbs often leads to more discoveries of vandalised pages on IMDb too. Since we can't trace things like this on IMDb and the staff is mostly unwilling to do it as well, using Wikipedia histories helps to track in some way when the vandals are vandalising both places.

See this IP range blocked by Wikipedia for 1 year for example. It can be seen from the edits clearly, it's surely the same person who's responsible for all the mess here on IMDb too. They promptly blocked it for 1 year, and most or all of his vandalism edits were already reverted. While same things were being reported here for months with no actual solution from IMDb (until it goes to the press).
