Welcome To BotScout

BotScout helps prevent automated web scripts, known as "bots", from registering on forums, polluting databases, spreading spam, and abusing forms on web sites. We do this by tracking the names, IPs, and email addresses that bots use and logging them as unique signatures for future reference. We make this signature data available through a simple yet powerful API that you can use to test forms when they're submitted on your site.

Stop The Bots

You can manually search our bot database to find bots in your forums, but you can also use a little bit of code in your forum, contact form, or other web application to test for bots and automatically ban or reject them on the spot. To make use of our database in your application, all you need to do is query it correctly. You can also download a list of the most recently-caught bots (shown below) from this URL: http://botscout.com/last_caught_cache.htm.

If you need to do more than about ~1500 automated lookups a day you'll probably want to get a free API key so you can do as many as you need. We even provide some sample code that you can use in your forums, contact forms, mailing lists, and other parts of your site.

There are also anti-bot plugins available for popular forums and CMS applications, including SMF, VBulletin, phpBB, Phorum, PunBB, Invision Power Board, FUDForum, Ikonboard, W-Agora, Wordpress, Joomla, and Drupal.

    Want To Help?

    You can help make life harder for bots by using the BotScout plugin on your site, because the more bot signatures we collect the more effective our filters become. Although we collect large numbers of bot signatures through our "bot honeypots", we can't catch them all. To submit bot data, all you need to do is get an API key and use BotScout on your site(s).

    You can also put a BotScout logo, button, or badge on your site to help let other people know about BotScout.
