I have used a keyed email address scheme since the mid 1990s (me_context@domain.org). 99% of the email I get now is sent to the same 5 addresses, in particular me_boingboing, me_linkedin. Those addresses were never on a web page. The keyed addresses I used for my company occasionally get spam, but it's generally on topic (offering relevant services, though still imo spam). I also have a gmail address that is a common first/last name but I don't send from that address, I get a lot of presumably guessed address spam there. This suggests quite a bit of organization in how spam works these days.
