on unfiltered infrastructure they cannot hide as they can now. They use it the clients can auto report without telling you if you choose such a hypothetical setting. Trading freedom and openness for fear and censorship is a non starterr for me. It is harder to do it from the client in a decentralized way at the moment but it is possible. centralization and attendant temptation / ability to censor is not something that we should be encouraging if we actually want an open internet experience.
How often do you see those things now? If you dont follow them you shouldnt see them. I dont. dunno why you would. leads me to say that user side tools can do the job and the community is not as dirty as some seem to say.
this could be as simple as an llm to prechew your feed for you that learns your preferences over time or as heavy as an extensions layer supported by privacy focused DVM's that you can use for heavy lifting if needed.
The point is that there are options that don't give back the decentralization we have fought so hard for.
