"Effective immediately, US Chess is publishing the names of US Chess members who have been sanctioned by our organization. This decision by the Executive Board was reached via an 8-0 vote.
Minors will not be named, but their sanction will be listed."
Most notably we see GM Alejandro Ramirez being effectively banned for life.
You can find the entire list in this Sanction list pdf
It’s surprising to see Timur Gareyev on this list. He is the World Record holder for most simultaneous games played blindfolded (48). I watched the live stream of this record attempt and it was mind-blowing. He’s well known as being a blindfold chess expert but he also does a lot of crazy stuff, like skydiving with a chess board: https://en.chessbase.com/post/timur-in-the-sky-for-chess-life
I can’t find information anywhere on what his rules violation was, but this PDF says “Violations of US Chess Safe Play Guidelines.” Those guidelines can be found here: https://new.uschess.org/sites/default/files/media/documents/us-chess-safe-play-guidelines.pdf
He was suspended for just 1 year, so I can’t imagine it pertains to the more serious types of violation outlined in that document.Edit: https://lichess.org/blog/ZNTniBEAACEAJZTn/breaking-the-silence
