You talk to bots on Amazon? If say Hacker News was entirely just bots, why would you bother commenting, why would you bother reading the comments?
I remember a sales person in a store actively trying to shame me for purchasing from a brand he didn't prefer. I gave him a lot of chances to get off of me, respectfully and firmly. Some really are like blood sucking leeches, they don't come off. He was probably paid to do that.
