UPDATE – I no longer recommend SweetCaptcah due to the fact that it's been revealed that the plugin is used to distribute adware. You can read this Sucuri blog post to learn more about it. I would uninstall SweetCaptcha if you have it running.
Do you hate getting comment spam on your WordPress blog? I just found a solution that might help anyone running a WordPress website, SweetCaptcha. Honestly I think this is the BEST WordPress Captcha solution I have come across so far. Even better than the widely used Akismet developed by Automattic (the company behind WordPress.)
What is Sweet Captcha? Basically it is an imaged based captcha (Completely Automated Public Turing test to tell Computers and Humans Apart) solution that asks users to solve a puzzle. While a lot of similar image based puzzle captchas I've seen are kind of annoying difficult and require too much thinking, SweetCaptcha keeps it simple.
Dealing with spam comments can take up a lot of my time. On one news website I help run we can receive thousands of spam comments every day. The reason for this is we get quite a lot of traffic now, and spammers obviously like targeting high traffic sites. I decided to try out SweetCaptcha. The result? It has stopped the vast majority of spam comments. There are still a couple that get through but the good majority are caught by Akismet.
In addition setting up Sweet Captcha was hella easy. I just installed the plugin from the WordPress.org plugin repository, provided my email, then a few clicks later it was up and running. Once I realized how great it worked on the news website, I installed it on several other WordPress sites I help maintain or run.
I've seen plenty of similar types of captcha solutions out there but usually they are complex and a pain to solve. Most of these captchas are great for keeping spam bots from commenting but… it also makes it so that humans won't either. Anything that takes a long time and is more hassle than they a potential comment thinks is worth it… someone probably is not leaving a comment.
Another type of captcha I hate, math. I HATE math so having to solve a math problem is a big no-no in my book if you want me to comment on your website. This shouldn't come as a surprise as most people hate math. Clients I work with that have math based captchas I recommend they remove them immediately. They always experience an increase in blog comments. Why do you want less people to leave comments? Sorry math nazis but people just don't like having to do math problems when leaving comments.
Honestly just as bad as math problems would be reCaptcha. This came from the useless minds at Google that only think of things how engineers would like them, not real people. Can anyone seriously read a what those words say? The problem is a lot of sites use reCaptcha, ugh.
Anyway, having to go in and delete WordPress spam comments in my websites is time consuming every day. So I figure SweetCaptcha will save me at least 1 hour or more a month since I won't have to do this on all my WordPress blogs.
My concern with SweetCaptcha, like most, is this might be too complex for some people to solve. There should be some complexity though to keep the spammers out.
Some of you might be checking the comments below and be wondering, “Hey, why isn't Adam using SweetCaptcha?” This site is run on a WordPress Multisite installation and I could not get the plugin configured to work. 🙁 Still I'm going to use SweetCaptcha on all my standalone WordPress sites. That is until I find a better WordPress spam fighting tool.
Like most WordPress plugins SweetCaptcha is completely free. The developers take donations to help support development and have some premium options so you can your own puzzles or strip out “Powered by SweetCaptcha.” You can add several sites to one account email address as well.
