I got tired of spammers having my information, so I built a tool that submits an up-to-date copy of my information to over 500 websites. Surely this will help.
Jokes aside, I unironically suspect the purpose of many opt-out forms is merely to record the up-to-date information.
How many of the forms have captchas etc?
How many require you to make an account or confirm your email address/phone?
Agreed. Any time I click an “Unsubscribe” link in an email, that takes me to a site where I have to provide my email or indeed, do anything more than click “confirm,” I leave. I assume it either resets some kind of consent trigger or sells my data to a new third-party vendor. The assumption of bad faith is now baked into my interaction with almost every corporate entity.
