You're not guilty by association, and I want to make a special point about this. I feel an ethical imperative to block people who associate with the True Guilty, such as Grendel. Without doing this, the problem of Grendel's creeping corruption of the hubski community will not be solved. He will have a second-order influence on the hubski zeitgeist through people like you who continue to interact with him. This is why I regretfully embrace the concept of collateral damage.

I share things that spawn decent discussions. Grendel does not do that. He is intentionally trolling the community. You are right that he takes an opposite view. He does this on purpose. I know his type. There can be no leeway for people like him, especially during such a critical moment in a community's history, with so many new users joining the site.

New users will see the things Grendel says, and even though they will see that he's 80% against the hubski zeitgeist, they'll think his behavior is maybe 15% permissible. So they'll maybe act in a 5%, or even only 2% way similar to him. But this error compounds and gets bigger and bigger as more users flood in. This is how Eternal September ruins communities. This is why reddit turned into a stupid parody of itself.

Grendel's behavior is 100% unacceptable. I don't want to have anything to do with him. I want my social graph to keep him 7 nodes away from me, not 2. If I don't block people who follow Grendel, then Grendel is right there, lurking right outside my vision, influencing my filter bubble through you and others like you.

I don't want Grendel to have any influence on my filter bubble at all. I don't want him to be a part of the community that I'm a part of. Hubski lets me tailor my community, and I am the sort of person who is willing to cut away some of the good flesh of the fruit to get rid of 100% of the rot.

I am morally opposed to blocking you, but I feel it is ethically necessary unless you stop following Grendel.
