I suggest making a website to blacklist the rude and profane gamers online. The rule would be simple: If a gamertag gets nominated for the list on 3 days in a month, it will be added. After a name is added, it's up to all of you, the community, to stop playing with the people who are on the list. Reinforce the notion that being rude and profane online will ruin their experiance, and they will stop. I would do this myself, but I have neither the time, nor the energy to keep the site running the way it would need to. Please, post any ideas or comments below, and thank you for reading this.
