There are many bad bots in Internet. Some of them scans your server ports some of them tries to inject malicious codes and cookies. And also there are many methods to block those unwanted bots. Everyone doesn’t have money to get a hardware based firewall to protect their servers,
Some companies claims that they have new way to block malicious traffic but they arent always reliable and accurate most recent example is this.
For wordpress there is a plugin called “Bad Behavior”.
Welcome to a whole new way of keeping your blog, forum, guestbook, wiki or content management system free of link spam. Bad Behavior is a PHP-based solution for blocking link spam and the robots which deliver it.
Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site’s load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.
Bad Behavior also transcends other link spam solutions by working in a completely different, unique way. Instead of merely looking at the content of potential spam, Bad Behavior analyzes the delivery method as well as the software the spammer is using. In this way, Bad Behavior can stop spam attacks even when nobody has ever seen the particular spam before.
Bad Behavior is designed to work alongside existing spam prevention services to increase their effectiveness and efficiency. Whenever possible, you should run it in combination with a more traditional spam prevention service.
Seems interesting right? I mean simple solution like installing plugin to filter bad traffic? Yes I thought that too and went ahead installed it and ran it for about a month.
But I didnt bothered to check the log recently. And I did today and found out that its blocking some legitimate bots like Amazon,MSN (Bing) bots.
So as the log it blocked MSN bot for about 1000 times. And I checked the wordpress forum about bad behavior plugin and found that some users complained that its blocking google bot too.
So think twice if you want to use this plugin!
