This captcha helps you not bother your users by asking them count the goats in the picture, arithmetic questions, re-write what you see in picture and more pathetic questions just to fill a form of registration or to comment.

It works on one of the most unique techniques which leave no doubt on its effectivity of filtering the spammy comments. It basically traps the spam bots by creating a hidden field that is invisible for the humans.

Since humans cannot see it, therefore, they cannot feed anything in it. However, the spam bots can see it and therefore they feed in it. Whenever any comment submitted to the blog, it checks whether there is anything in that field or not? If yes, it marks the comment as spam and notifies the admin without saving it. It is rated 4.8 out of 5.

3.    Blue Captcha:

4.    Anti-Spam Plugin:

The fourth anti-spamming plugin that we have on our list is the Anti-Spam plugin developed by Donald Knuth. The reason of being on list of top anti-spamming plugin is that it does not bother either the user or the admin to block spamming comments.

It means that it does not show captcha to users to fill and also does not notify the admin about deleting or considering the comment. It rectifies the spam on its own and deletes it automatically. You can determine its effectivity by its rating which is 4.5 out of 5.

5.    Anti-Spam Bee:
