Somebody hates me $5 worth

There is a website—one that is so stupid I feel embarrassed to even give it free publicity—called www.whotohate.com. The idea behind the site is you pay them five bucks, write in the name of someone you hate, and the website writes to the person telling them that there is someone who hates them.

I got one of those hate mails today, meaning that someone hates me enough to be willing to pay $5 to have me receive such an email.

It is an interesting product they are providing from an economic perspective. Does the person spending the $5 get utility from the act of declaring (albeit completely anonymously) their hatred? Or does the utility come from the (real or imagined) pain on the part of the recipient when he or she discovers the depth of another’s hatred?
