"Aaron
1. If the name contains a word that would get you in trouble if you wrote it on the board in a school classroom, don't do it.
2. If it is the name of a person reviled by millions of people because of their actions or beliefs, don't do it.
3. If someone in the game could see it and say "This is over the line", don't do it.
4. If you were going to use another managers actual name and they wouldn't find it to be a friendly joke, don't do it.
If you are warned about a name, please take a few minutes before creating your next name to think about whether or not it's worth the time trying to find the line between acceptable and offensive. It will have been noted that you were warned previously and we really don't want to see the same people showing up repeatedly.
Now its crystal clear.
Be Civil Guys :D
