You don’t mess with Craigslist, apparently.

A fan-run blog called Craigslist Blog has been served a takedown notice from the massive classifieds site, according to a post from blogger Tim White on Thursday.

White posted the e-mail he’d received from Craigslist CEO Jim Buckmaster, which claimed that White’s URL “craigslistblog.org” was “infringing” and that its name was “needlessly confusing to members of the media and the general public, and must be changed.” Buckmaster did not demand that White stop blogging, but he did request that he stop using the domain, turn it over to Craigslist, and additionally stop posting excerpts from Craigslist on the unofficial blog.

In response, White agreed to stop excerpting Craigslist content, and the unofficial Craigslist Blog now prominently displays the phrase “(the unofficial one)” in its masthead. But White wouldn’t back down on the domain.

“I think you have received bad legal counsel and that this is potentially a really bad PR move for (Craigslist),” his e-mail response to Buckmaster said, an allusion to the company’s friendly, hippie image.

Buckmaster seemed none too pleased with White’s response, and in a second e-mail that White posted to his blog, he reminded the blogger that Craigslist’s law firm of choice, Perkins Cole, “also does intellectual property work for Google, and for a lot of other prominent companies.”

When White launched the Craigslist Blog last month, Craigslist did not have its own blog. That’s changed recently, as Buckmaster now authors an official Craigslist blog. A report earlier this week estimated that Craigslist’s annual revenue is likely around $80 million and could be significantly higher, except that the company is “not about the money.”
