Bing displays some "best"-type list results generated using AI
Bing.com displays "best"-type list results generated using Artificial Intelligence from multiple "sources around the web" for some queries in a very similar way to Google's Knowledge Graph (with some of the same citations used by GOOG for similar queries). Google displays citations for each result in their list while Bing just provides a handful of citations for the whole list.
It would appear that these search results (like other information from sources around the web & like Google's Knowledge Graph results listed as "from sources around the web") are not factual. Thus they can be low quality and manipulated by spammers. There are also issues with some lists cited in these results on Bing : e.g.
some lists are arguably low quality without review ratings / review content / review criteria - some are just descriptive lists with no "rhyme or reason" on a "reputable domain"
non-Bing guideline compliant links to some of the citation list pages - these lists are (partially) generated presumably with Chat GPT (which does not abide by Bing Webmasters guidelines).
