They could make it so a player meets certain requirements before a vote is possible, such as inactive for 10 minutes or so. Other criteria such as bad behavior would be hard for the system to measure - or impossible even. Also players shouldn't be kicked for being inexperienced or playing poorly as long as they are trying. I have a feeling this is going to be limited to afk-ers. And equipment requirements are going to be implemented, so that's a non-issue.
