Every day, I see absolutely moronic comments getting upvoted while perfectly reasonable takes are downvoted. This would be a great opportunity to curate your feed by blocking these users en masse. Active curation like this is the only way to make social media even half-tolerable.
Whether you use it to filter out toxic users or to build an echo chamber, I think everyone should be free to do so. No one should be forced to share space with people they feel bring no value to the discussion - or, worse, make it more toxic.
Nobody is saying to you that blocking shouldn’t be available. They are saying to you that blocking large numbers of people to create a bubble is harmful to you and the wider community.
Hence blocking people who agree with a certain post is going too far. The action is too heavy handed for the “crime”. It would be a harmful feature. It’s"shooting people in the head for laughing at an edgy joke" levels of heavy handedness.
My blocklist is already over 500 users long. I don’t block people for disagreeing with me. The bubble I’m building for myself is a bubble free from unreasonable assholes.
However, you didn’t really answer my question. Blocking an entire instance is already a feature. That’s way more ‘heavy handed’ than what I’m suggesting.
