This goes back to my early days on the internet, but: I do not use blocklists or ignore features except as an absolute last resort. Ignoring the problem is not a solution. In other ways I think it just makes the problem worse. If the person is not banned from the community, then your decision to pretend they don't exist just leaves other people to deal with it. Instead my feeling is that you should confront it by lobbying for their removal, or leave the community.

Sure, you may no longer see the noise, but that means that newcomers to your community do and have to deal with it. When you have a giant blocklist, you are ignoring your duty to police your own community.

Then there is the issue of people blocking people who are simply more tolerant than they are. Hiding speech that is challenging to your personal views is a different kind of disaster.
