Some websites that I have trialed in the past year are so persistent and annoying with their update newsletters and feedback requests that I consider them spam. It's even worse with small services where the founder will try to stalk and cold-call me and I have to tell them to F off on the phone ~_~

Also, most websites get hacked sooner or later, so even if they themselves are tolerable, they might leak my data to spammers.

As such, I treat everything asking for email address or phone number as an adversary. I usually setup a new username alias per service. That way, I can reconfigure the address to become a spam honeypot should the occasion arise.

For example, I'm getting boatloads of spam to my old Adobe Creative Cloud login email. I must have been included in one of their security fups.
