Know if there's any way to block entire servers when they're as toxic and low-quality as the one you mentioned? So far it seems like the only way is to browse 'all communities' and get rid of them one by one

Yeah, pretty much (GPT-4's a big upgrade over the default 3.5).

That said, OpenAssistant is already really impressive for a project with such limited resources. Would love to see open-source overtake OpenAI quickly (which IMO isn't out of the question, considering how quickly Stable Diffusion developed)
