Spam…You probably hate this word, don’t you? If you are a website owner or a blogger you likely have some kind of web forms, and if you do, you know not by hearsay how terrible and annoying spam is. It is a big problem when spammers try to make use of your web forms for their unkind purposes, so the first thing you have to think about is how to prevent a spam spreading and do it in such way that won’t complicate forms filling for your visitors. You need to find a perfect balance between a comfort for the users and web forms reliability and now we will take a look on 8 efficient ways which will help you to forget about spam attacks once and forever.

Before we get started, it is worth noting that there are 2 types of spam. First one is spambot which is programmed to abuse all web forms it can reach, leave comments about some product and spread the links. The second type of spam is organizing manually by people who were hired to spam targeted sites. It is more difficult to divine their actions because they can get around the defense systems. So, first of all, you need to get a good contact form which will provide all necessary means to protect your site form the spam. Now, let’s get back to it and consider the ways that will enhance the spam protection:

Install CAPTCHA plugin

CAPTCHA is one of the most prevalent and popular ways of spam blocking. This script is designed to generate randomly selectable texts or more complicated expressions which are displayed in such way that makes it hard to decipher it for spambots (in some cases even for the humans as well). If the user enters the data correctly he will be able to fill in the form and you won’t be overwhelmed with tons of spam, but do not overdo with CAPTCHA. Set it on the most significant forms, otherwise, your visitors might be scared away by constant verifications.

Captcha vs ReCaptcha: What to Choose?

Do not use auto-responders

When a user fills in the form he can get an automatically sending Email with words of gratitude for registration or something like that and this is a powerful weapon for spammers. Instead of this you should better reply to everyone personally and disable auto-responders to prevent “over spam”.

“Honey Pot” – a trap for spambot

This method is based on the statement that bots cannot recognize CSS or JavaScript, so it is possible to create the forms that will be invisible for the customers but “available” for the spambots which can read only the HTML. The robots will be attacking the HTML with a couple of prepared Emails while the real forms remain intact. But be careful, spambots are getting more complicated, so there is no 100% guarantee that they won’t circumvent such defense.

Limit the login attempts

You can reduce the spam number by installing Limit Attempts plugin which will allow you to set the number of failed login attempts and block user’s IP, so you can stop automated scripts and protect your website.

Use test questions

The idea consists in putting a simple question which would be easy to answer for a human, but which will cause the problems for the bot. It is usually a simple math problem or a well-known question like “What is the color of the tomato?”. If you get an incorrect answer, you’re probably dealing with a spambot (or a guy, who doesn’t know how tomato looks like, which is very unlikely), so block the access and stay calm.

Try to embed session tokens

Considering that bots don’t set cookies, you can prevent spam attacks by setting the session tokens. If the session cookie wasn’t set on the form, so only the people will be able to fill it out because the most of spambots attack the forms directly and this measure will help to get rid of them.

Use special tools like Akismet

Akismet is an efficient tool that will help you to block spam on your forms. Generally, it is very popular among the bloggers because the tool is doing its job great when you’re dealing with comment spam, but the other forms can be protected too. The most distinguishing feature about Akismet is an ease of use, so you can set it on and relax while it will defense your forms automatically.

Check your IP filter

When you receive a spam you can get the IP addresses from which it was sent. A list of these addresses will help you to monitor and filter the incoming requests so the next time you could deny it and protect your forms from spam attacks.

Conclusion

The spam problem is getting more and more actual for the website owners because spam programs are constantly improving and becoming more sophisticated and compound. The most efficient way to struggle with spam is to use different strategies and do not focus on a certain method, but use the advantages of several ones. In this way, you can provide a versatile defense system, which will become an unapproachable wall for spam.
