I notice that there is a list (shown at the end of the post) in the chatroom called "CURED" for nominating closing and deleting questions from the main site.
This search shows that such lists have been written almost every day since 2018, mostly by one active user. So far there have been 900+ such lists. Questions on such lists would mostly be deleted soon. Some are relatively old and some are quite recent.
This chatroom seems quite popular on the site and I consider such lists are encouraged by the chatroom users.
Is there any generally applied algorithm used in the CURED chat room for nominating closing and deleting questions? Are these lists generated by certain SEDE queries (e.g. restriction to some length of the body, dates, etc.), or are they picked from the Q and A pool using the so-called "Enforcement of Quality Standards" of the site?
The possible "algorithms" found in the chat room are in the following two messages:
I do not know though if they have ever been upgraded or not.

The actions in bulk from the chat room make a great effort to collaborate closing and deleting questions. This has been done for several years as the record show. If this action is a very good thing for the community, showing in public the standard they use, (again who has done more than 90% nominations of the very popular chat room), could draw more users' attention and more users join them. It is currently very unclear what algorithm they use.
@robjohn mentions that "The guidelines they are working from are outlined in "Enforcement of Quality Standards". Nevertheless, the EoQS is "published" on Apr 28, 2021; there are obvious 2018 or even 2015 questions in the deletion list.
