Musk fired most of the moderators, and those messages are being sent automatically after a certain time period. I did an experiment before - searched for phrases like “death to nationality” and “kill all nationality”, with various nationalities, and reported a dozen each to check if there is any bias: There isn’t, all of them were ignored. I believe any moderators left, if there are still any, work by the queue of most reported first, and the top of the queue is most likely filled with brigaded reports from right wing trolls.
