What about people who speak to one person as if they are responding to a thread. AR maybe, scores to settle perhaps, using "us" for sure but generally waste our thinking efforts when we don't have the clues to their hidden agenda?
Might I respectfully suggest the term Agenda Vendor
these things being what they are I'm sure if there is a need for the title it will fall to the community that is "the 'cat" to evolve one anyway.
Yes! It is an issue with me currently. (don't want any hidden agendas from Mr Open-red-handed-tactics do we?)
