Google the term "hellban".

No, seriously, google it. I'm not just giving you the name, unless I'm looking at an overpersonalized search results page, the result page is a fair gateway into both sides of the controversy around the practice as well.

The way that trolls are made invisible on Thought Ocean isn't really analogous to hellbanning; it's closer to how people who aren't your Facebook friend are invisible to you on Facebook. Thought it's still pretty different from that also.
