By the way, Leo. Thank you for the httrack info. Very interesting.
I usually take a snippet of text from my site that is particular to my site, type it into Google in quotes, and can find any other site that is using parts of mine. Most of the time I find the text on those index type pages that have many links to many sites, with the Google ads all over the place. I have not found any site that is a mirror of mine, yet, thank God.
Many of the images on my site can be found in Google Images, where they find their way to all types of forums as hotlinks. I have that blocked in htaccess.
The only other issue that has been happening of late are the typical hack attempts trying to login to the admin through the categories directory. (admin/categories.php/login.php) Those types of attacks are also blocked. They get the 403s. Thanks to jdMorgan for his help. Thanks also to Bill; lots of valuable info from him. These have no referer, a variety of IPs and a variety of user agents. Lots and lots of those within the last two weeks.
