1. Your reply to Blue was just a bit rude. You can't tell the staff and others not to ask about how they would enforce this. Even if you aren't a member of staff, you still have to have some type of good idea of how exactly this could be applied and enforced. You are the one to propose a rule, you have to also have a plan to go with it.
2. Youtubers cannot control how fans act. This is not them taking advantage of the fans. And in case you haven't noticed, the fans want to team and help the youtubers. They aren't asked to.
3. There are 200 servers alone in the U.S. You can complain all you want about youtubers teaming with fans, but do you really expect them to turn around and kill them all? That'd be rude to their fans and could possibly lose them subs. So, if you have a problem, like I previously mentioned, go to a different server. It isn't too hard.
Lastly, again, you should really just let this go. There are multiple reasons why you shouldn't have bothered with creating this thread. You don't even have a plan as to how to enforce this rule, so null. You're practically just raging about youtubers having fans that want to help them out. You're being rude and calling people out just for disagreeing with you. So, as a member of MC Gamer community, I'm simply asking that you try and be more respectful and polite as to what others have to say, myself included.
