New, from me:

"In May 2025, the U.S. government sanctioned a Chinese national for operating a cloud provider linked to the majority of virtual currency investment scam websites reported to the FBI. But more than a month later, the accused continues to openly operate accounts at a slew of American tech companies, including Facebook, Github, PayPal and Twitter/X."

tl;dr: The tech industry is all over the place in terms of how or whether they will take down accounts tied to sanctioned individuals. For example, GitHub has a policy of locking but preserving accounts tied to sanctioned individuals, but there is very little left to indicate that the code in question was produced by a sanctioned person and maybe shouldn't be forked or used in production.
