100,000+ podcast episodes have been submitted with incorrect country name. Possibly done by Nomissimon10.

I discovered that a large number (nearly 100,000+?) of podcast episodes have the release date with incorrect country name.

For example, this is an American podcast shows, but it is displayed as having been released in Norway.

Norway 28 September 2018
https://www.imdb.com/title/tt16865852/releaseinfo
Norway 15 October 2018

Next example, the podcast show from "German-speaking area", not limited to German-production, but it is said released in Norway.

When it comes to Norway, I also noted that an one of last year's Top 250 contributor, an account named Nomissimon10 (Simon Lyngar) said, he wrote an automatic computer program and submitted a lot of info. So he made a mess of it.

Here: https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/imdb-top-300-data-contributors-for-2021-and-happy-new-year-2022-from-imdb/61d013ded8944f34de691c4e?commentId=61d0161b7daadb4938f1c18b&replyId=61d0e924e4279c627b17b5b9

He said that he copies information from Spotify, but many podcast websites (including Spotify) are often incorrectly displayed release date without proper handling of time zone differences.

IMDb staffs should check all the submissions he has made and correctly change or delete release dates. It is like kind of a vandalism.
