Kicked for no reason..

I was playing on DC server while ago.. map DM-Flatfinal and players ***Z-E-U-S***E and 1_Imposter votekicked me from game for no understandable reason. I think they did it because I shieldguned players EMaster and HMaster out of safe place, who were afking for almost whole match.
Also player 1_Imposter was somehow scared when I tried to shieldheal him O.o
Not sure what is wrong with those dudes but it should be investigated.
