WP:Jagged 85 cleanup

A major cleanup is ongoing relating to Jagged 85 (talk · contribs) who has made over 87,000 article edits since 2005. It has been found that many edits involve the undue promotion of Islamic and other non-European scholarship and achievements. In addition, there has been a severe misuse of sources: misrepresenting what a source has asserted; reporting only one side from a source; quoting out of context; inventing claims using a source related to the topic but which does not verify the claim.

Jagged 85 was indefinitely blocked on 17 September 2012, and was community banned on 22 September 2012 (ANI permalink). The cleanup lists below show all article edits made by the user.

Cleanup procedure

Pick a page from Cleanup lists (below).
For example, Cleanup1 currently starts "Antisemitism: (18 edits, 7 major, +131825) (+128)(+131)..."

"(+128)" is a diff of an edit by Jagged 85 which involved adding 128 characters (large additions are in bold because the tool used to create the links is intended to highlight possible copyright violations).
Check what text was altered by the edits.
Often, there will be many edits in one or two small sections regarding ancient or medieval history. A useful approach is to use the diffs to see which sections were edited, and which sources were added: those sections and sources in the current article need to be carefully checked, particularly for claims like "X was the first to...".
Assess whether the current text satisfies relevant policies such as WP:V, WP:NOR, WP:NPOV (particularly WP:DUE in WP:NPOV).
If necessary, remove or refactor text as required. Per WP:BURDEN in WP:V, where there is reasonable doubt, text should be removed pending a demonstration on the article talk page that the text is verified by reliable sources. In your edit summary, include a link to this page so editors (possibly after several months) can find the background. Some example edit summaries are:

failed verification, see [[WP:Jagged 85 cleanup]]
unsourced, see [[WP:Jagged 85 cleanup]]

Update the entry on the Cleanup page. To do this, keep the "Antisemitism: (18 edits, 7 major, +131825)" text, then replace all the following diffs with either:

{{n}} ~~~~ (if you found no problem at the article); or
{{y}} (optional explanation) ~~~~ (if you found some issues, but cleared them). It is helpful to add a brief explanation of how you cleared these issues in parentheses, e.g. (removed irrelevant material), (removed unverified material), or (added reliable sources).

These display respectively as either:

N your signature; or
Y (optional explanation) your signature.

2022

Note that Maestro2016 (talk · contribs) was blocked as a Jagged85 sockpuppet in 2022. Maestro was an exceptionally prolific editor, being one of the top editors of the site by number of edits. He may have been somewhat more restrained in his use of sources, but a list of articles heavily edited should probably still be scrutinized.
