I've seen big old gobblers turn away from a strutter decoy, even a red headed jake that they didnt get close enough to identify as a jake...other times they came in fightin'...they are like people in the fact that they have a wide range of personalities.
In my experience, if a bird is a fighter, he'll come to a jake decoy just as fast as a gobbler decoy.
Most jake decoy floggings I've witnessed were by 2 year old birds anxious to bully someone around....kind of a payback for all the floggings they took last year I guess.
As far as the putting goes, they saw something they did not like...not necessarily you, maybe the positioning of the decoys.
