Played in this server yesterday. Some medic on my team ubered a guy who was obviously new, who, while ubered, attempted to push the cart (as blue). Ubered people can't push the cart, so after I spawned, I attempted to say, "You can't push the cart while you are ubered, so you should always run as far ahead as possible and clear things out."
While I said this, some asshole started mic spamming over me, basically telling me to shut up and making fun of me for trying to help somebody.
I told him to stop being such a dick, muted him, and then told the dude again what I was saying so he could hear it without interruption.
That asshole then votebanned me for "mic spamming".
An admin was there the whole time and witnessed the whole thing.
If admin allow assholes to take advantage of a feature like voteban to ban people who are being friendly and helpful, it earns a vote as "bad server" in my book.
