TORONTO - The RCMP says it's working with Craigslist to try to stop erotic ads from being posted on the company's website in Canada.

Some believe those ads are a cover for prostitution.

Craigslist shut down its adult services section in the United States on the weekend and replaced it with a black bar that says "censored."

That was after a group of state attorneys general said there weren't enough protections against blocking potentially illegal ads promoting prostitution.

But as of yesterday, the Canadian site still had an "erotic" link listed under its services section and the Mounties want that to change.

Craigslist officials could not be reached for comment.

But back in May, CEO Jim Buckmaster said the company's ads were no worse than those published by the alternative newspaper chain Village Voice Media.
