I don't see a rel="nofollow" attribute on the link to the original post, or a meta tag in the page header(?). (Logged in or not.)

Oops, there was a bug in that code that I just fixed.

Could you elaborate? I thought the story was somewhat in the hacker spirit in that it exploited the oft-overlooked option of retaliating against spammers.

pg is doubting if this story is true, and thinks it might be a nice "stick it to the man" story. Since it's linked here it might be a SEO attempt to get a higher Google ranking for words like "telemarketer".
