To mark a site as spam, click on the spam link below the title of the site. This will place the site in your own personal spam slashtag. The sites that you mark as spam will no longer show up when you search on blekko (while you are logged in.) If you place a site in your spam slashtag in error, you can manually remove it by going to your profile, clicking on the spam slashtag, and deleting the URL of the site you wish to remove from the slashtag.
