As it is not mentioned by OP : anime site it's speaking about is HiAnime.
Excerpt :
HiAnime, the world's biggest anime piracy streaming site, is now one of the newest additions to the U.S. government's annual list of notorious piracy and counterfeiting markets.
Can't believe it's someone's job to make this list and this is what they came up with. A 14-year-old with internet access could name way more major players.
It sure is nice of the US government to compile a list of sources for us https://ustr.gov/sites/default/files/2024%20Review%20of%20Notorious%20Markets%20of%20Counterfeiting%20and%20Piracy%20(final).pdf
If they keep attacking all my favorite streaming sites then I guess I'll have to finally figure out this torrenting and Usenet thing.
No! The more of you weirdos that switch to the clearly superior form of piracy, the more they'll go after p2p sites.
id imagine Sony is behind this given they have the most to lose from anime piracy specifically in the U.S
