Ok the part you are referring to was specifically in reference to the concept of these one liner spambots. They are using a particular tutorial. They are like pets whose owners have abandoned them. That tutorial relies on a websocket connection to this site. Close that particular hole, even just checking user agents strings and those strays are euthanized.

People that would go to the trouble of standing up a node etc, are a different class all together and we treat them differently by giving them direct incentives to build better bots.
