Mistaken identity crisis

I've had my rather distinctive email address going on six and a half years now; thanks to my tech-geek friend, I was able to score one of the first gmail addresses out there when it became available to non-tech people like myself. Unfortunately, it seems that a number of people have not gotten the hint that my email address belongs to me, and only me, and I have been receiving over the past few months weird emails from different services that I have supposedly signed up for. As of right now, there are at least three individuals out there who are either incredibly stupid, lazy, or are cursed with the inability to spell simple words repeatedly. And its not as though this is just email newsletters or the like clogging up my inbox; I've received email messages from one individual's mother, another containing rather sensitive material such as the person's mailing address, phone number, and bank information from another woman in Georgia who apparently recently purchased a house, and the most recent has come in from chemistry.com. I've had it about up to here dealing with these morons, so I decided to do something rather passive aggressive about it. I logged into the chemistry profile with the information provided to my email account and updated the profile to this:

Is it mean? Maybe. But I'm hoping that it will get the point across to this person once and for all that they keep entering the incorrect email address over and over and over again. Some people's kids. Sheesh.
