I basically give companies 0 strikes anymore, and assume the "unsubscribe" link is at best, a dark pattern that only unsubscribes me from that 1 out of their 100 "channels," and at worst, confirms my E-mail address. "Report Spam" immediately.

I unsubscribe twice (allowing for one possible bug), then spam.

And, as others have noted, unsubscribe cannot involving going and logging into their system. If I need to do that, it generally goes directly to spam.
