Hotlinking is simply not cool. Referrer spam is also not cool. I get both of these from 4 Blogspot sites, and have struggled to contain their mess. The problem is that they are hosted by Google, through their Blogger platform, GoogleUserContent.com. Though Blogger is free, they are very difficult to kill. Here’s what I did to combat the problem.
Using Blogger as a Referrer Spam Platform
Puzzling, it is at times, that my htaccess does not always behave as intended. As a computer scientist I expect that my programs and file input should output consistent, stable and reliable results immediately. This is not the case with my htaccess file, hosted on Site5, my internet service provider.
Delays in htaccess Implementation
When I do certain changes to my htaccess, there may be delays of a day or two. This is very odd to me, because supposedly the htaccess is checked for every server request. Maybe there are some caching that I do not know about. Nevertheless it seems like the htaccess has a unique personality. I know that I should not anthropomorphize a computer, much less a security file such as htaccess on an Apache server, but it is difficult to not.
