Have heard the worst thing you can do to someone is ignore them so I have no trouble ignoring them.
Different context.
You as a single individual can ignore them. But when they descend on websites such as FR, you cannot communicate because all the posting is taken over and normal posters get overwhelmed. That is the disruption they aim to achieve. I have witnessed it here and elsewhere.
They can be defeated by asking questions that mess up their programming and also expose their artificiality so they can be zotted.
