Comment SPAM Bad Neighborhood Analysis (2013-Mar)

We track and block a lot of comment SPAM via our WordPress plugin and our CloudProxy WAF. One thing we noticed is that the majority of the SPAM we detect come from the same “bad neighbors” (IP ranges that are known for sending a lot of SPAM).

We did a little query for the month of March (just in 23 days) and these are the top 20 networks used by comment Spammers:

# of comments sent | IP range

Those 20 small network blocks were responsible for more than 230,000 SPAM comments sent to the sites we are monitoring (that’s almost 20% of the total that we blocked during the same period). And if you are curious on what were the most common SPAM were, these were the top 5 messages for the month so far:

#1: 6861 SPAM comments had: Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization.
