I wrote “because I don’t to” or something as the reason, which was immediately accepted.

Looks like multiple hurdles to discourage people from opting out – the notification without buttons on, form to fill in, verification PIN code by email you need to enter.

To be fair, without the PIN you could opt-out everyone you knew without their consent.

Only because of their clunky form that requires an email input rather than infering it from the logged in account.

I’ve tried multiple times now and still haven’t received a PIN.
