As MP4Moviez and CoolMoviez continued to thrive, the authorities began to take notice. In 2017, the Indian government launched a crackdown on piracy websites, including MP4Moviez and CoolMoviez. The sites' operators responded by changing their domain names, migrating to new servers, and employing more sophisticated evasion techniques.

The site's operators, who remained anonymous, seemed to have an uncanny ability to stay one step ahead of the law. They employed various tactics to evade detection, such as frequently changing domain names, using mirror sites, and encrypting their content. This allowed MP4Moviez to flourish, attracting millions of visitors from around the world.

The entertainment industry has responded by investing in anti-piracy measures, such as content protection technologies and awareness campaigns. Additionally, many countries have strengthened their laws and enforcement mechanisms to combat piracy.

The final blow came in 2020, when a coordinated effort between law enforcement agencies and industry stakeholders led to the shutdown of MP4Moviez and CoolMoviez. The sites' operators were tracked down, and their servers were seized, rendering the sites inaccessible.

The shutdown of these sites also had a significant impact on the entertainment industry. According to a report by the International Federation of the Phonographic Industry (IFPI), the global music industry saw a 10.4% increase in revenue in 2020, partly due to the reduction of piracy.
