I like that the MIT CSAIL CSS website (https://css.csail.mit.edu/) has a link to a Russian online gambling site due to what I’m assuming is a typo (click on the Foundations of Cryptography class)
Likely it was an expired domain. I have seen this trend happen quite a bit with semi-popular domains, e.g., International Olympiad in Informatics 2019 official website, ioi2019.az
