I have a fun one. I own syslog.com (since 1997) and I get all kinds of email sent from mis-configured routers and other devices meant to write to syslog, but somehow it escapes and ends up in my inbox. The problem with that is many times these are automated and poorly configured, so I'll get hundreds of emails a minute from really badly broken setups. I generally email support at the domain owners but most of the time I have to blacklist them at the server.
