 This has been going on for quite a long time. By that, it has now been
 years. Every few weeks to a month we have to delete our error log as it
 builds to become an incredibly huge file on the server. So far, there has
 been no resolution to this anywhere. We have tried the forums and so many
 other places which have recommended starting a ticket as clearly, we
 aren't alone in experiencing this. There has to be a way of preventing
 this.

 This causes huge stability issues and consumes a LOT of space on the host.
 Therefore, I feel this has earned the privilege of being considered
 "critical". I filed under "database" although this may be better under
 something else as it seems to be some kind of injection attack using
 search engines and fake links that try to load content into the blog via
 error or search results, etc.

 Here is (believe it or not) a very small sample of what the error logs
 hold every time...

 (see attachment, as this would be far too much to paste into the post)
