CAN ANYONE HELP?

Since September 09/08/2006 one of my blogs has been invaded by a blog burglar/hacker who has posted repeated advertisements to the edit post page. Blogger has been of no help at all and advice by computer savvy people has been unfruitful in stopping this pest. Even though my edit post page has been cluttered with 18 (so far) adverts, I have not yet deleted them in case the urls will help track him. I have not accessed any of the urls, either.
