Google inURL spamarama attempt
There's an option when you perform a Google search called inurl (this is one of their advanced operators) meaning the web address contains [this]. Several IP's from RIPE (of course) have been spidering my site looking for random numerical sequences which are typical of many blog software programs.
Older blogs (like mine) archive html documents starting with zeroes and then the number of the document afterwards. For example, this one is #875 and the permanent link web page will be 000875.html. The typical directory for archived things is called archives. What the spammers are doing is Google searching for inurl:archives/000875.html or something similar, then spam it later by method of bogus comments and/or trackbacks.
Here's an example of a Google inurl search for the term archives/000800.html. You'll see that a ton of results show up, indicating nearly all those sites are blogs.
Fortunately I don't have to worry about this because I have trackbacks and comments turned off. In addition to that I also physically renamed the Perl script files that do those functions.
This is yet another reason why I don't have trackbacks and comments enabled.
