Why Should I Block websites?

In our daily routine, we visit a number of websites for our required information regarding Office work, education work, or for some entertainment.

On those websites, some websites are vulnerable to our data and privacy. Some websites steal all your information through login data and some websites are intended to attack the users with malware software. Along with these, some specific websites will irritate us by continuously sending unwanted notifications. In that situation, we should think that it’s better to block those websites to prevent all these problems.

The concept of limiting access to websites arise due to addiction. Here are a few reasons why to block websites.

  • Excessive usage of social media which eventually affects productivity.
  • Moving away from work by browsing entertainment stuff.
  • Block unnecessary and adult websites for children.
  • Sometimes it works as a security measure as well.

YouTube kills productivity at workplaces and the same with social media websites and the list goes on.
