5 ways to block bots on site forms
Forms are a fundamental tool for collecting information on the site. However, they can be subject to intrusion by bots, which can send spam and damage the security of user data. Here are 5 ways to protect your site's forms from bot intrusions.

CAPTCHA authentication
The CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a technology designed to ensure that a request comes from a human and not a bot. There are two types of CAPTCHAs: visual and audio.
Visual and audio CAPTCHAs
Visual CAPTCHAs present an image with garbled text that the user must decipher in order to submit the request. Audio CAPTCHAs present audio with words or phrases that the user must listen to and repeat in order to submit the request.
Google reCAPTCHA integration
reCAPTCHA is a CAPTCHA solution from Google that ensures form security and helps protect your site from spam and bot intrusions. It can be easily integrated into your site's forms to ensure the security of user data reCAPTCHA uses a combination of technologies, including user behavior analysis and image recognition, to determine if a request is made by a human or by a bot.
Check with safe questions
Testing with safe questions consists of inserting customized questions that only a human can answer correctly. These questions can be generated randomly or chosen by the user himself when registering.
Check with custom questions
Custom questions may be based on your personal information, such as your birthplace or pet's name. This makes safe question verification an effective way to prevent bot intrusions.
Limiting Requests
Request throttling is setting a limit on the number of requests a user or IP address can send in a given period of time. This prevents bots from sending many requests in rapid succession, which is typical of bot intrusions.
Limit of requests per user and per time
The request limit can be set both per user and per IP address. For example, you can limit it to a maximum of 10 requests per user per day or a maximum of 100 requests per IP address per hour.
IP address reputation rating
IP address reputation assessment is another way to protect forms from bots. This involves using black and white lists of IP addresses to identify bots and prevent them from accessing forms on your site.
Use of black and white lists of IP addresses
You can use blacklists of IP addresses known to be associated with bots to prevent access to your site's forms. At the same time, you can use whitelists of trusted IP addresses to ensure that legitimate users have access to forms.
Integration of a security software
Integrating security software like Akismet is another way to block bots on your site's forms. These software use advanced algorithms to detect and prevent bot submissions, ensuring the safety of the forms on your site.
Choosing reliable software
It is important to choose reliable security software that can effectively prevent bots from sending requests. Check customer reviews and ratings before choosing a software and make sure it has been tested and proven effective in blocking bots.
Ensure security for you and your users
In conclusion, protecting forms from bots is important to ensure the security of user data and to prevent invalid submissions. Using a combination of these 5 ways, you can block bots on your site's forms and ensure a safe and reliable experience for users.
