Having a Captcha Plugin on a WordPress.com Site
-
My blog, Colltales.com, doesn’t have a pluggin menu, which I’ve found out, it’s because it’s a .com, not a .org. But I think I, and everyone else, could benefit from having a Captcha plugin, to prevent Spam posts that routinely invade my blog.
Perhaps, there’s already a way to install it on .com sites like mine, but I couldn’t find any info about it. Thanks and regards,Wesley Coll
The blog I need help with is: (visible only to logged in users)

You will find most people here strongly disagreeing with you as CAPTHA actually discourages comments and makes it completely impossible for the visually impaired.
Besides, WordPress.com has an excellent spam filtering system in Akismet. In the two years I’ve been blogging I only once had a spam comment, while it has filtered over 4000 successfully.
Make sure that under your comment settings you are requiring visitors to either be logged in, or to enter a name and email address to comment. Disabling these requirements will open your blog up to more spam. http://support.wordpress.com/settings/discussion-settings/#before-a-comment-appears
http://en.support.wordpress.com/unwanted-comments/Additionally, Akismet is a learning engine, and if you consistently mark spam messages as spam rather than deleting them, Akismet will learn to recognise that spam and start filtering it out automatically. Likewise, if you approve spam messages as real comments, Akismet will start allowing them through the filters.

Thanks for your input, Kokkieh. I didn’t realize that installing a Captcha filter would restrict access to the visually impaired, which it makes it no longer an option. As for Akismet, I agree that’s a pretty good system, even though I’m not particularly interested in how many posts it catches, but the ones it doesn’t. And it does miss a half-dozen a month, in average, even though that I do have the email requirement to posters checked. Some spammers seem to be always a step ahead of Akismet and I’m often surprised how these ‘messages,’ which are so similar but not enough to block them as a whole based solely on their verbiage, get through. Anyway, it may not be too big of a deal; just an irritating factor of having to go through everyday, spamming them. Thanks again.

Chances are you’re dealing with human spammers. They can sometimes fool the system. If you keep consistently marking them as spam it should decline over time. Under Settings ->Discussion you can also set your spam filter to strict. That might make a difference.
