My block list grew slower once Voyager implemented user tagging. Most of what gets blocked now is porn stuff. I don't mind it existing (and have an account just for that), but there's certain stuff that just isn't my bag, baby.
And yeah, I'll tag people as trolls/agitators, bigots, headline bots (even if there's a real person behind the account), [insert political label here], etc. I'll still block if I feel the need to, but a nice yellow and black "warning" tag lets me know to just not engage, and why.
Edit: you may need to go into settings -> user tags and enable them first.
