I decided to take a detailed look at the daily access logs, and see whether any post in particular had been requested a lot. Well - there was one specific page request that had a lot of requests. So I tried bringing it up, but no dice - it didn't exist. Not only did it not exist, but the request page ID (which is actually a timestamp), refers to a very strange date:
June 4, 1911 19:05:36.000
Well. I don't know about you, but I wasn't doing much blogging 50 some odd years before my birth :) I took a look at the referers - yup, they were all for pr0n sites. The impressive thing is, that out of 813 requests for this (non-existant) page, 654 of them used a different IP address as their origin.
I must be popular - I've got my own spammer :)
