Risky … if it’s automated, they could argue that you’re not actually making a conscious decision and/or not actually doing it yourself, claiming that it doesn’t apply or isn’t an unambiguous indication of your intent to knowingly opt out of whatever the next revision of the arbitration clause may be. It’s far more unclear how that would play out in (US) court than with a manual opt-out once per account per terms of service revision.
