Yeah don't take votekicks personnally.... The tremulous community is full of retards(naturally there are many good players as well).
Standard "reasons" for votekick: they accidentally chose you instead of a deconner, you are better/worse then them, you have higher/ lower ping then them, you said something in the wrong language (polish takeovers of server:P), they need to starts a vote kick so they can decon and disrupt gameplay without being voted out right away, you get under the feet of a tyrant(known as blocking), you are playing with the name unnamed player, you die too often? and the list goes on....
