Every website with a newsletter that you can't unsubscribe with just one click, but instead you have to log in, and go to settings, and select the fucking unsubscribe option, should be BANNED from internet!
In most cases this kind of website is unusable with a smartphone, or at least only the settings page is not responsive, to make it more difficult to fucking unsubuscribe.

I'm trying to unsubscribe from a fucking website since 2016, but every time I open the email with my smartphone it's just impossible to do it, and I forgot every time to do it when I'm using a PC.

Now, after a few months I received this fucking SPAM when I was using my PC, but I forgot my password, and the recovery password option just doesn't work, so I still can't do it!

If you're one of these fucking developers, there is a special place for you in hell.
Even if the decision to make it so fucking dumb isn't yours, you are still accomplice, because you should have leave this fucking job.
