For a few months there have been these referrers whose website links don't end in ". com" and they have repeated views on my blog (a wide range from 3 to 20 views) which is really strange for a visitor. I noticed that they would search in my blog the keywords of titles of the blog posts, and that for the posts they searched for, there would be Google ads near the bottom of the post, above the comments section. These ads appear in my blog on Internet Explorer and Mozilla Firefox, when I'm not logged in.
I'm guessing they hacked my blog and put ads on it to make money off when someone clicks on the ads.
Is there any way to stop these "referrers" from coming, or to take away the ads?
The blog I need help with is hernotepad.wordpress.com.
