> One spammer said they could use the same servers for both but when you unsubscribe you have immediately signaled that you are now losing him money. So he uses the slowest cheapest part of the stack for removal.
Hmm, wouldn't you want to remove the money losing people as soon as possible, so you don't waste even more money on them?
Doesn’t compute.
He probably meant that “customer” is not making him money, therefore not worth the time. The only reason unsubscribing works at all is probably a legal requirement.
It does, probabilistically. For any given customer C, the expected value EV(C) is... not much. By starting an opt-out process, a customer Co is revealed to have EV(Co) = 0, which is less than not much.
