Revise the ToS to Allow Multiple Accounts
Honestly I can see no reason why this is in the ToS. Supercell does not enforce it, and it is commonly known that they do not enforce it. The major YouTubers invited by Supercell to Finland all have multiple accounts. They openly make videos with multiple accounts, and Supercell does nothing to stop them. Clearly, they don't feel like they need to.
So why have this there? The only thing this is doing is scare people into creating a new account, when Supercell doesn't frown upon it or care about it in the slightest.
