This MI5 guy has been spamming multiple lists/groups - aircraft, ham
radio, electronics, photography, and likely many others that I don't
subscribe to...
Complaints to the list administraotrs get no response...

Anyone know anyone who can get some action to block this guy?

His ISP is a notorious spam facilitator, so don't expect any help from them.
