Pranked

Someone signed me up on the email lists for Tom Tancredo and Duncan Hunter. I'm assuming it was a prank, as my political views are pretty clear:

I confronted the person I thought was the most likely suspect, who laughed. He did think it was a great prank, and began signing his left-wing friends up, and signing his right-wing friends onto Dennis Kucinich and Hillary Clinton's email lists.

So, readers, is this a good prank? Or is it rude?
p.s. I'm finding both Hunter and Tancredo quite amusing.
