7 Best Captcha Plugins or a Turing Test: Reliable Yet Readable

If you have ever faced a problem of spam comments, you must know how irritating it is and how much of your precious time manual filtering can consume. Luckily, the range of WordPress plugins which have been created by this time, can solve almost any problem.
Using a captcha plugin is one of the greatest ways to get rid of this spam-trouble.
The word Captcha stands for Completely Automated Public Turing Test to Tell Computers and Humans Apart. It’s a great antispam measure which stops spam comments, spam emails and bot registrations.
Being a great barrier between you and spammers, it may also become a barrier between you and your readers, which is why sometimes funny cases caused by Captcha may happen.
For instance, several days ago I entered Crocoblock office and saw my co-workers talking. One of them was agressively typing something and the other one asked him:
– What are you doing?
– Fighting with Captcha.
– And who’s winning?
– Captcha!
However,  sometimes Captcha is the most efficient solution. So if you feel that this is your case, check out the best Captcha plugins for WordPress.
