How Much Does Spam Cost?

The true cost of spam can be hard to quantify. There is the cost of the time spent cleaning up spam, which I recently wrote about on another blog. (In that post I determined that a few simple anti-spam measures had saved me $20,000 worth of time after just over a year.) Another cost of spam could be lost members or advertisers because of the inappropriate content that gets posted on your board. Still another cost of spam could be an entire board. How is this possible?

Just how big is the spam problem? 10,000 posts and counting

If you are wondering why the idea of bbProtection was conceived then this is the post for you. Dave and I have been running some honeypots to catch spammers, their trends and their general behaviour for a few months now and its time to give a general idea on how things are going and just why we are running them.

New Style of Comment Spam

One of many podcasts that I currently subscribe to is the Geek News Central podcast by Todd Cochrane, which runs alongside his successful site at geeknewscentral.com.

I noticed a post by him citing a new type of comment spam that he and others had started to see happening on blogs that they own and manage. This new style is working to try and hide the links that spammers are attempting to push onto sites, mostly by linking them via a single character on the comment, so that it isn’t obvious when just browsing through the comment itself. Todd’s post also goes into some detail about how spammers try and gain a sense of trust before starting to put links into their posts. I’d recommend reading the article, it’s certainly interesting to hear his thoughts on the spam issue and new trends that he and others are seeing.

Bots are relative easy to beat but if spammers are using real people to leave relevant comments linking to their spam sites this will be a bigger challenge.

This quote was of interest to me because it goes a long way in summing up what bbProtection is and just why it works. When checking and filtering spam you need to actually check what is being submitted rather than who is submitting it. Of course, certain checks on a particular spammers IP range or other details relating to the submission can prove useful when checking if a post is spam or not but if a system is checking the actual content of the post then spammers are going to find it increasingly difficult to get their posts and registrations through the system.

bbProtection is designed with the bulletin board in mind but we would of course welcome anyone to use our open API to design a system that works for different blog packages as well. However, more about that in a later post 8) .

Dave’s Spam Talk at Londonvasion 2008

For those of you who aren’t aware, Londonvasion 2008 was phpBB’s first conference style event. Our very own Dave Rathbun presented about the spam problem facing board owners and his attempts to try and prevent it.

The presentation is well worth a watch and is also downloadable from the Londonvasion page, under the [08] phpBB Spam header.

Dave explains a little more about the content of the presentation over at his blog, so go and check it out :) .
