When I go to Dashboard > Blog Stats, I'm seeing alot of my "Top Posts for (the date)" listed as "#11724 (deleted)". Over and over, with a different number. Almost all go to a daily post on the website (URL link format shows as http://www.mysite.com/?p=11724, for example) but many take me to various spam websites.
The site doesn't have comment registration or allow commenting. Our site traffic has been pretty consistent and doesn't seem higher or lower than usual. Can anyone help with pointers on where to look to see what's wrong here? I haven't a clue.
