They already reversed course on that decision a couple of days later. Trivial to find a source, but Fable is also rather notably not available to the public right now, so it's not actually a relevant threat.
That’s totally unrelated. The post I was replying to claimed that if you create a new account with OpenAI and that gets detected, your whole account gets silently “nerfed”.
That is not in any way related to Fable (visibly) being switched to a less strong model if you’re trying to discuss certain topics.
Reddit is the only platform that actually tells you that you are shadowbanned, so at least they are upfront about it, but their appeal system sucks. My friend just appealed every day for just over 600 days and finally got their account un-shadowbanned.
