How can I completely avoid someone here?

Like I blocked them but I still see their topics, questions, things everywhere, they are literally EVERYWHERE and it's kinda annoying cus it's a group of people who all have this particular word in all their usernames and they act the same & oh god did I mention everything they do is annoying?! Apparently blocking only forbids them from replying to my stuff but I just want them out of my sight. HOW TF DO I DO THAT?
