11
+ == Description ==
12
+
13
+ This plugin will add a client side generated checkbox to your comment form asking users to confirm that they are not a spammer.
14
+ It is a lot less trouble to click a box than it is to enter a captcha and because the box is genereated via client side javascript that bots cannot see, it should stop 99% of all automated spam bots.
15
+
16
+ A check is made that the checkbox has been checked before the comment is submitted so there's no chance that a comment will be lost if it's being submitted by legitimate human user.
