I'm getting multiple spams every day from nitwits who buy spamming
packages that include a list with one of my addresses in it, and then
they spam me from throwaway accounts at one of the big providers.

Since the mail is technically 100% legit the spam filters have to look
at the body and since they tweak the body every time, that's a losing battle.

This is illegal in Canada and the UK and the EU, but these are mostly in the
US.  I do get occasional spam from the UK who I never hear from again after I
send the form letter asking for details for my complaint to the information
commissioner's office.

R's,
John
