After my previous post on the subject of comment spam, I decided to use the might of Google to see how many sites have fallen prey to comment spamming bots.
Given that the phrases “my parents didnt told me about it” and “think that will make relief” are pretty obscure; I was confident they would produce accurate results from phrase searches.
Below are approximate figures based on what Google tells me, most are mixed with ‘normal’ sites in the results due to Google’s PageRank:
“think that will make relief” - 80,200 results
“my parents didnt told me about it” - 88,800 results
“thins that excited you at 14” – 87,200 results
“substances that cure you” – 82,400 results
“black girls on their mission” – 77,700 results
The sites spammed tend to be Blogs (Wordpress, MT etc.) and Forums which don’t require any user-signup.
Interestingly, the bots don’t appear to have any direct benefit to spammers. The links they post are mostly to ‘mainstream’ websites like www.apple.com etc.
However, I suppose if I were the spammer... I would probably use this as a method to locate all the sites with open-comment policies to abuse at a later date.
