Protect Against Web Spam
Typically various “Internet SEO Companies” try to leverage poor forum software protection against mass submission and create many worthless posts with links to a website they are promoting.
Some forum and blog software implement various CAPTCHA solutions but these have two negative aspects:
- They annoy your visitors.
- They provide a fake sense of security.
- Today it is possible to buy access to API which solves any kind of CAPTCHA for just $0.70 per 1000 CAPTCHA images solved by a real human being. And do you really think your customer will be happy to try to solve one of these ridiculous CAPTCHAs?
Secure Against Brute Force Attacks
Many modern applications are susceptible to brute force attacks. Take a typical login form, for example. Hackers can compromise account security by trying every possible password combination. They can also leverage a large network of proxy servers to paralelize this attack. Forcing their browser to work hard makes it too expensive and slow for hackers to perform a brute force attack.
