Like you say in my before topic “All of WordPress.com ads are family-friendly. If you feel an ad is inappropriate please take a screenshot of it, upload it via Media -> Add New to your Media Library. “
The image is in my Library and it called Advertising. Then, can removing this advertising my blog?
Those ads are not placed on your site by WordPress.com. They are being placed there by software on your own computer, unfortunately. Notice the text below that says “Ads not by this site”? These ads are sometimes caused by malware or a virus, but more often it is due to a browser extension or toolbar that you may have installed in your browser.
