Ask HN: Automatic binding-arbitration opt out?

I've been seeing an increase in notifications from various service providers about changes to their terms of use, often including the addition of mandatory arbitration clauses for which there is a 30-day opt-out period. It would be great to have a service that connects to my Gmail account, identifies notifications like these, and automatically sends a snail-mail opt-out request on my behalf.

Is there anything like this out there? It feels like there's a more generalized class of problems that this falls into, where consumers are placed in a suboptimal default state, and opting out requires some minimal but non-zero amount of effort. Sort of adjacent to the "call Comcast every 12 months to renegotiate my cable bill" problem (for which services already exist). Are there similar unsolved problems that fall into this class that could be addressed by a single service?
