If you are talking about vote kicking, then no, there is no such thing as a penalty for it. It does not matter why someone was vote kicked. It could be their class, their transmog, the direction they ran, the way they play. It does not matter. There is no such thing as “abuse of vote kicking” in the rules. ANY reason is valid to kick.
Unless you meant that people can’t use malicious language such as profanity/masked profanity, slurs, etc. That would certainly get penalized if reported.
It does not violate any in-game systems or rules. The game is set up, intentionally, so that the majority can vote to remove a player for ANY reason, or no reason.
Edit
There is even an entire support article explaining that a group does not need a reason to vote kick someone.
