A bank might suspend your checking account if it detects suspicious financial transactions on the account. The goal here is (ostensibly) to protect the account owner.

Google, as per the precedents it has repeatedly set, could suspend your checking account for participating in a stream on YouTube and following the streamer's instructions to spam chat with emotes in order to vote on his path through the game, as happened to Markiplier and his followers. That's far beyond what anyone should consider reasonable risk for being able to access their bank account.
