Spam is a solved problem ... unless you're on Typepad. There are great services out there like Akismet and Mollom that take care of spam entirely, without even bugging the user with CAPTCHAs. I haven't seen a single spam comment in a year if not more (thanks to Mollom, in my case). You should check if you can add one of these services to your blog here.

Adding rules manually may sound obvious when you get a number of similar spam comments, but in practice it's not feasible. There are so many different things that spammers post about, and so many variations that the only reasonable defense is to have something that notices similarities across lots of websites. Also, adding some brand names is one thing, but once you add words like shoes and jewelry and drugs and lots of synonyms, you start creating false positives.

Rick Wicklin

Agreed. Unfortunately, it's sometimes hard to filter on names. For example "Medford Risk Management" sounds legit, but is actually spam. There seems to be a subtle combination of name, website, and content that enables an observant human to detect spam, whereas algorithms might miss it.

And, of course, no IT staff wants to deploy an algorithm that has false positives (blocking valid comments) since that angers the users. But as you point out in your book, balancing the false positives and false negatives is a tricky business that necessarily requires trade-offs.

My Movable Type blog gets tons of spam that's not caught by the filter (and, of course, the filter sometimes traps real comments). I'm switching to Wordpress.

Ron's Log

I have a Typepad blog and long ago I stopped expecting any results from their filters (if they have any). I've been manually blocking for a long time and gave up on getting any results from sending suggestions to Typepad. I got one reply to a suggestion that essentially said "Too bad, that's just the way it is."

Ron: I have also voiced my discontent many times and so I thought maybe I can shame them into doing something about it. Apparently not. On twitter, they told me to block those IP addresses manually, which is the same robotic response they give every time I point this out.

Since Robert tells us spam filtering is a solved problem, how difficult is it for Typepad to buy the technology to resolve this issue? The fact that they haven't is an indication that they don't care. This attitude is shocking since unlike others, they charge money for their software.

One day, I'll take Andrew's advice and quit.

The only way to do is make the comment form is only for facebook account and others social that have login API key which can integrated with blog you have. So when spammer come to your blog to make a comment, they'll thing twice. They can't put their link on your comment form except only their profile page of their social site.

Of course some realise their mistake and attempt mid-course correction – Mercedes (now following lower price high volume strategy), Star bouquet of channels (which is regaining its number one position through revamped programming and positioning, after it had lost to Colors), Coke (which realised that every experiment to undermine Thums Up was actually benefiting Pepsi more than Coke), and many others.

So, let complacency not consume your brand. You may not get a second chance to regain lost ground.
