    “Solve Media” captcha is freaking ancient, unusable, greedy oxymoron to permit spammers to protect us against spam

      @DonQuixote: I might not agree with the usage of words, but I do agree with the message you are conveying. As I mentioned in the article, that is the reason I am also not using Solve media.

    Don’t forget about Mollom as well. Instead of only separating the wheat from the chaff, so to speak, Mollom uses a third category. If It’s positive — by analyzing the text, the poster’s IP address and its past behavior, the links in the post itself, etc., that the post is spam, the post is blocked. If those same characteristics lead to the impression that this is a good poster who’s been well-behaved throughout the intertubes, then the post is accepted, no questions asked. If Mollom isn’t sure (and only then), a CAPTCHA challenge is created and displayed, and the post’s status will hinge on whether (if) that CAPTCHA can be successfully answered. This has the advantage of blocking the bad folks, not punishing the good folks through constant CAPTCHA challenges, and only using a CAPTCHA when necessary.

    Mollom is free for low volume (or even moderately high volume) sites, and is a backend service that works with lots of different CMSs. From a client perspective, it’s certainly well maintained on the Drupal side,but there are also many other quality clients — including WordPress! — that can be viewed on Mollom’s download page.

      @Keith: Thanks for the tip about Mollom. It indeed looks good. I really like the way their pricing is structured. They give 100 legitimate comments free per day. That is not something that a lot of websites get (even I fall in the free category going by number of legitimate comments).

    @Ishan, all Internet is overfilled by prepaid articles on Solve Media “genius” captcha though a dozen of companies offered the same long before SolveMedia in less annoying and more secure way. All my comments on SolveMedia, for ex. in http://blogs.wsj.com/venturecapital/2010/09/21/an-online-ad-that%E2%80%99s-tough-to-ignore/ , are being promptly deleted. Thanks for leaving them here. The words are just the words, but actions and facts are more important

    In my case I have just installed Akismet and captcha. Those are the two plugins that I currently use and good results but I am seeing a huge amount of feedback is going to be moderate, so it might take some of these important choices. Thanks for this valuable information.
