No worries about the accounts, you will probably never see them again unless I test something else out. Please do not ban me for doing this, I am taking care to make sure I am not breaking any rules by doing this(keeping it unranked, not using an account that I use to actually play). Also there are no rules against having multiple accounts. This would not be sandbagging, score cheating, escaping, or playing yourself in ranked games, therefore it is not illegal to do this at all.",
