There are those who are somewhere between flamers and trolls. They are the ones who try to embarrass others, manipulate them into making replies they don't want or need to make and get them jumping around at their beck and call.

I would call these 'baters'. Spelt that way. It means those who seek to get folks flapping their wings wildly or frantically, a term used in falconry.

They nearly always do this from an anonymous position.

The only way to deal with them is to withdraw from any dialogue with them at all, no matter how provocative.
