I'm curently receiving up to 100 spam a day lately and I've come to the conclusion that sending abuse reports via #spamcop doesn't work; nobody actions the emails (observing same IP addresses sending spam over a long period despite reporting abuse via spamcop)
But...using spamcop to analyse the #spam is useful, since it's very good at providing the sender IP and ISP. I then do a whois on the IP and often find there's a website to report the abuse to instead. I've had better results this way.
Got a response back from Microsoft telling me that a Costco-impersonating email from 40.107.94.115 "did not originate from a mailbox associated with a Microsoft account" and "Unfortunately, we are unable to take action against e-mail accounts that are not within the Microsoft network." WTF?
This morning I received spam from a mortgage broker to a personal email address. They have never asked me for permission to email so I wanted to report them to the email provider they are using.
Step 1: Who is it? To find out I had to take the links in the email, do a WHOIS to find out the owner (obfuscated, of course!), then trace that to another domain which finally led me to Campaign Monitor.

@gozzy Spamcop finds the who and reports the #spam, based on the email headers. Cost is minuscule, I think I paid them $10, 10 years ago? Not perfect, but works pretty well, and, helps out everyone else that uses the #Spamcop#DNSRBL
