Home | Internet & Businesses Online | Forums Forums like e-mail are the most vulnerable as they get a lot of spam. The administrators of websites are caught up with this problem. They spend hours trying to devise news ways of tackling spam. You need to have the right security to keep bots away otherwise you will be caught unawares and get hit by a ton of spam. You need proper knowledge of how forums work in order to keep spam at bay. First of all, you need to implement some small security measures to save a lot of trouble, such as getting people to register before they post on a forum. This is absolutely essential to stop drive-by posting, which sends people to links with pornographic material. But how do you register them? It is not difficult at all. You ask people to identify numbers and letters from a graphic during the registration process. This is enough to distinguish between a human and a robot, because a robot cannot fill out a form in such a manner. So the question of creating fake registrations will not arise. Sometimes this doesn't work though, simply because human spammers will sign up and send out the spam that way. Oftentimes people are hired in third world countries for very low wages to send out a multitude of spam. So what do you do in this situation? One way to control this is to have the administrator approve every registration that goes through. You will see once you do this, that you'll get 30 to 40 attempted registrations each day that are from spammers. Sometimes spammers can figure out what graphic is displayed during the registration process and the robot can actually answer the question with the right answer. A clever way some forum administrators have gotten around this is to install a modification that will ask the bot certain questions that only a human can read, comprehend, and answer. Because you can change the questions and answers, it can be different for each forum and robots won't be able to catch up to you. All you need to know is whether the registration is a human or a robot. You can get a confirmation about this through their e-mail address. This is the simplest way to know whether the registrant is real person or a robot. Article Source: http://www.articlewheel.com
