+ === Growmap Anti Spambot Plugin ===
2
+ Contributors: commentluv
3
+ Donate link:http://comluv.com/about/donate
4
+ Tags: comments, anti spam, spam, spambot
5
+ Requires at least: 2.9.2
6
+ Tested up to: 3.0.1
7
+ Stable tag: 1.0
8
+
9
+ Defeat automated spambots by adding a client side generated checkbox asking the comment author to confirm that they are not a spammer.
10
+
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.
17
+
18
+ You can get support and see this plugin in action at [Growmap](http://www.growmap.com/growmap-anti-spambot-plugin/ "Growmap Internet Strategist")
19
+
20
+ == Installation ==
21
+
22
+ Wordpress : Extract the zip file and just drop the contents in the wp-content/plugins/ directory of your WordPress installation and then activate the Plugin from Plugins page.
23
+
24
+ WordpressMu : Same as above (do not place in mu-plugins)
25
+
26
+ == Frequently Asked Questions ==
27
+
28
+ = Does this plugin add any database tables? =
29
+
30
+ No.
31
+
32
+ = Will this plugin work with Disqus/Intense Debate/js-kit? =
33
+
34
+ This will only work with the default Wordpress comments system.
35
+
36
+ = If I disable javascript will it still work? =
37
+
38
+ No. This plugin requires javascript to be enabled in the users browser for the comment to be accepted.
39
+
40
+ = The checkbox doesn't appear in my comment form =
41
+
42
+ The checkbox only appears for logged out users.
43
+ If you're logged out, it only shows if you have javascript enabled.
44
+ If you are logged out and have javascript enabled and it is still not showing then you need to have the comment form action active in your comments.php theme file
45
+ ` do_action('comment_form',$post->ID); `
46
+
