Oh man, I never realized how common my First name, Middle Initial and Last name were until my place of work linked a bajillion small email empires in one humongous ldappery.
Wrongly directed emails from people became endemic, and some contained very sensitive info. I ended up writing a mailbot to deal with persistent offenders, though after a particularly annoying exchange with the other me, in which I attempted to enlist his help avoiding the problem in the first place and he belligerently and persistently refused to understand the problem, I removed the logic that forwarded the mis-directed mail to him and replaced it with a boilerplate "your mail was sent to the wrong person and has been deleted unread" return-to-sender message.
Half the problem was the exchange mafia who didn't put very much info in the exchange "address card" and refused to allow people update permissions on their own info. Their solution, when asked to add one line to my card pointing out my location in a different city to the other me, was to offer to change my email name. They densely refused to understand that this would solve nothing and add a further complication that now no-one who knew me and needed to mail me would know what my address was. It was maddening.
One persistent mis-mailing person was in charge of a small staff, each of whom - for whatever reason - felt inclined to respond to any email from her just to show they were paying attention. She would send out a mailing to "all" (including the wrong me) and include a metric clucktonne of attachments (all eyes-only, sensitive stuff). Said staff would then reply to all, including original attachments.
I went home one Friday evening, and at eight o'clock my teenytiny mailbox crashed with the overload from one of her missives and it's echoes. I came back on Monday to find eleventy thousand mails from the exchange boyos yelling that my mailbox was full (though how they thought spamming me every five minutes with their mails over a weekend was "helpful" I don't know).
So I wrote a special bot for her and her cabal. Each email I got from someone on her "reply to all" list got their email and attachments back at them, with a copy sent to the original offender.
"Alice" would send me a mistaken mail with four or five phone book sized attachments. My bot would send it and its payload right back with a "Wrong Stevie again, Alice" cover letter, and delete my copy. Then a veritable hail of incoming mail c/w 4-5 phone books would begin as each of her staff members would say something like "Me too" or "I agree" or some other totally worthless observation. I would bounce each one back to the sender along with its payload, and send a copy to "Alice" - with payload. There were about ten people on her staff, so each time she initiated hostilities she would end up with eleven distinct sets of phone books, all the same, which would collapse her mailbox and cause eleventy thousand emails from the exchange quango to swamp her mailbox over the weekend.
It still took three salvos of tripe before she started being careful about which Stevie she claimed as a subordinate.
Any time someone says "I know where you live" in a threatening manner, I respond "I bet you don't" and let them harass random not-mes they found using Google searches. This does not work with police officers standing in the rain while holding my driver's license I've discovered.
Then there was the time I got a call at home from a lawyer wanting to sue me over my driving an ambulance I do not own into a vehicle I had never seen in a city I had (at that time) never visited en route to a hospital I had never heard of. It took another lawyer to explain that lazy database searches on name alone were not the basis for a sound lawsuit, even in New York, nor a reasonable basis for slanderous accusations of criminal liability.
But that's a tale for a different thread.
