The physical mail spammers know to only use deceptive tricks, like "FINAL NOTICE" or pretending to be affiliated with you using some publicly available information. I have not yet seen one dare to full-on lie, because there would be real consequences. If a scammer puts "FINAL NOTICE" on a solicitation they mailed with no prior relationship, I do still report it as fraud. But that's probably wishful thinking.
