Agreed. There are better blocking/muting/filtering systems, and worse ones. Implementations also vary widely. For example, I think the design of filtering on Tumblr is perfectly fine, including keywords, but the implementation is garbage and stuff from blocked users "leaks through" in reblogs. It would be great if there were a widely agreed-upon set of principles (preferably not a formal standard) for how such features should work, but I'm not aware of any. Then again, it's very far from what has ever been my professional specialty so maybe I'm just missing something.
