An easy way to reduce comment spam

[Join us @ facebook]

I've just realized that the majority of comment spam bots using a very simple way to spam our web sites.

They are actually crawlers who surf the web and post the same data (or random data) to each page they visit.

So a typical post will use the same variables to post - eg. comments, url, site, website, name, email, mail etc - and the very easy way I found that works is to use random variables.

For instance instead of using in your form a field with the name url, you can use a field with the name CSDO432A

I know it is too silly, but it worked even with bots that are able to read verification images....

I'm sure that this will work but on the same way you're remove some accessibility from your website:

think about automatic fill options fro forms and screen readers, next it is more difficult to code complex forms...

(this is working very well, or is this spam bot also good in adding numbers )

To be honest my first intention was to do something like that what you mention.

But as in the time of the development I was getting about 50-100 spam comments per day, I wanted to do something quick, and I thought this as a start.

The cool thing is that it worked instantly, so I haven't added anything else to check if this is really working, and the good thing is that it is

don't get me wrong using random field names is not bad, but I will never use it with forms with more then three names.

maybe this is the solution:

Code:

<?php
$name = 'uwur';
echo '<input type="text" name="'.$$name.'" />';
?>
