I once ran qmail as shipped in SME server (before they replaced the
receiving component) and it would routinely get hit by dictionary
attacks - which it would accept and then fall over as it filled its
outbound queue with bounces.   That list of 'accepted' email addresses
must have been sold and reused for years because the affected domain
continued to get about 50k/day of emails to those non-existing users
until the domain name was retired (for other reasons).  I switched it
to sendmail with a virtual user table for the few real user names so
it was able to reject the bad names almost instantly.

So, based on that, I'd guess you are on some of those lists that still get used.

Well, you did mention something that could be construed as violent -
by someone with a complete lack of a sense of humor.
