I imagine that poor old Kes had a trigger nightmare which involved him running out of a herb or something.
Hence the mass spamming you received was made all the worse for him by the fact that he was getting the spam too and he had the problem of trying to fix it in the middle of a fight.
When that happens to someone I'm fighting, I am thankful for an easy win 9 times out of 10.
Maybe, just maybe, it wasn't intentional! *wink*
