Cleo Integrals in the Math StackExchange

a very mysterious person in math.
Basically, there is a Cleo person, from about 2013-11 to 2015-12, answered about 39 super difficult closed-form integration questions on the mathematician forum Math Stack Exchange, in the unusual manner of simply posting the solution sans any detail. And provided a false user profile saying that she has medical condition as the reason she doesn't provide proof or explanation of her terse answers. Of course, all her answers are correct. This pissed off many mathematicians on the site.
But she disappeared after 2015. never logged in her account again.
here's a video made in 2023 that explained the situation.

Cleo did ask 2 questions, though.

Cleo's Profile on Math Stackexchange
Cleo's profile on math stackexchange, as of 2023-05-10. Apparently false info.
![cleo profile 2023-05-10 BtH5K](i/cleo_profile_2023-05-10_BtH5K.png)
her purported “medical condition” is apparently fake, because back around 2015, people in the forum have pointed out, she used to say something about being her religion to give naked answers.

Aftermath as of 2023-05-10
Looks like the people at math stack exchange are erasing history. They deleted comments on cleo's posts. Now it's empty.
