i received this very enticing email today: (one of those trying to sell you a domain name similar to one you own)
The domain name example.com is for sale, which is similar to your domain and may help in driving organic traffic and improving SEO. There are also 0 global searches via Google per month. Not to mention that advertisers are paying $0.0 per click.
I've been racking my brains trying to figure out how you can make the sender-- assuming it's a machine-- melt down. If you feed it some simple formulas based on its own numbers, you should be able to trick it into trying to divide by zero :(
