That seems a bit ridiculous since you can immediately cancel it if you’re only in it for one month. It seems like they want to link payments to account so they can ban all accounts of specific boters at the same time that are on one payment source. I’m going to guess that they also want to ban people who are using other regions accounts. Like Chinese and Korean users who play on the American realms. If they have a contract coming up for someone else in China it would be a big push they would need to get the Chinese players back off the American realms.
