REHAB

@Brahadeesh What I mean by annoying duplicates is stuff that tends to be asked over and over ad nauseum and can be easily redirected to an existing question

@AlexanderGruber: I think <100char is still a very good PSQ indicator.

"stuck" seems quite specific to PSQs. "really stuck" is even more specific. I do not think any real mathematical question has the phrase "really stuck"!!

@MartinSleziak Look for the text "enter image description here" and flag anything with that text and less than (say) 150 characters total?

Since Collatz was mentioned, it reminded me that maybe "vixra" could be another keyword to use when looking for "suspicious" posts.

Also one could check the words suggested when discussing autofilter for HNQs: Autofilters for Hot Network Questions and Which words (if any) in the title of a question should prevent inclusion in the HNQ list?.

@skillpatrol Regular expression help for Alex... bros?

[annoying duplicate] 1+2+3+... = -1/12

[annoying duplicate] 0.999999... = 1

Yes-- I've been quite busy with the election and some other things. This project will be returned to soon.

I have a question though. It seems that I shouldn't delete it so fast, so that it is harder for these cheaters to repost them again after the first one was deleted, since others can still see the first one.

I wonder if certain mathematical topics should automatically get extra scrutiny? While there are, for example, good questions which can be asked about the Collatz conjecture, most of the questions on MSE related to that conjecture are not very good.

"Sir" or "Madam" may also be worth flagging in conjunction with other indicators of low-quality, particularly in the comments. These typically indicate that the user doesn't really understand how the site is meant to work.

duplicates Another frequent duplicate: Questions asking about various special cases of $\sqrt{c+\sqrt{c+\sqrt{c+\cdots}}}$, or the limit of the sequence $x_{n+1} = \sqrt{c+x_n}$. math.stackexchange.com/questions/linked/115501

[crank] "Collatz" :P

[crank] "help" "urgent" "weird" "tricky" "hard"

Checking the linked questions is a reasonable approximation of duplicates. I'd guess that something could be also done with SEDE.

room topic changed to REHAB: Help Alex write regex to autoflag questions. Seeking multiple examples of common duplicates, and phrases that appear in crank questions and PSQs (no tags)

Every tag has frequent tab - that could be a candidate where to search for questions which are asked frequently.

@AlexanderGruber A few sentences might also be worth adding into room description. (Option to edit room-info should be available to room owners and to users with diamonds.)

@AlexanderGruber: Perhaps you can use List of Generalizations of Common Questions as a source for your list.

@Brahadeesh Mainly canonical abstract duplicates, but I would appreciate anything that seems easily identifiable with regex
