I didn't expect you to prevent it, but if you really want to know my alternative, scrap the cloud ban idea.The idea has changed a lot since the initial post.
I'm sorry about your friend, but I have nothing to do with McBans. We will try and succeed where they have failed.
There is no preventing this movement, but if you would like to offer an alternative that may help develop the idea further.
You've already told me you can provide means to gather evidence of bans. Have ore ratios, have logs, have whatever you like, but for God's sake, keep bans localized.
