Plagiabot (which runs as User:EranBot on the wikis) requires Python 2. Around October 16, it stopped adding change tags to revisions that were copyvios, meaning they are no longer surfaced in Special:NewPagesFeed (aka Page Curation / Page Triage). This apparently is because it was using the now obsolete method of fetching tokens in the MediaWiki API. For now we have commented out the relevant part of the code, but we'd like to get the Page Curation integration working again.
This task proposes a quick fix to implement the new method of fetching tokens directly into Plagiabot, since we are stuck on Python 2 at the moment and can't upgrade to the latest pywikibot. The real fix is to upgrade to Python 3, tracked at T293688: CopyPatrol: port Plagiabot to Python 3.
