having multiple account isn’t against TOS, why would it? All different accounts, all yours. It becomes a problem once you use login info of other players’ accounts.
I personally am thinking about creating a new account to do it myself for once raiding becomes inevitabaly less popular and getting groups is harder
Also, i hate the ‘i play for my kids’ while their kids honestly don’t play-people once they bring 5-or 6 accounts (i know a few of those). Those are the same people that fill up a gym screwing their own team. Just be honest and say you have multiple accounts, don’t come with lame excuses. Having 1 (or even 2) extra accounts is nothing problematic (even when it’s ‘your kids’) but don’t overdo it.
