For one example of many, they permanently banned an autistic live streamer for asking a question about how the Reddit Live algorithm works, claiming it was "harassment toward the admins." In reality, they've been brazenly and repeatedly lying to everyone about how the algorithm works for over a year, including selling ads based on grossly inflated viewership numbers -- and "grossly" is honestly a huge understatement. But folks who mention the algorithm in any negative context tend to get banned permanently, or at the very least censored from using certain words, such as algorithm, admin, mod and ban.
There is no conceivable way that spez is oblivious to all of this, so it's safe to assume that he put his stamp of approval on the behavior, either intentionally or by inaction.
Except for Huffman (spez) who still works there and doesn't seem to care whatsoever.
