It can happen that you identified infringing webpages before they were picked up by Blasty's monitoring system. Feel free to submit Blasts for them manually.
You have two options.
Paste the URLs of the infringing webpages into the "Submit infringing URLs" section of your account.
Visit each webpage and click on the Blasty extension icon of your Chrome browser.
The Blast banner will show up and let you blast the webpage.
