This is the most straightforward risk. Accessing and downloading copyrighted content from a site like FilmyFly is a violation of the Indian Copyright Act. While casually streaming may not immediately land a user in prison, repeated illegal downloads or sharing pirated files can lead to prosecution. Production houses like Yash Raj Films (YRF) and Dharma Productions, as well as streaming giants like Netflix and Amazon Prime, have filed numerous lawsuits against such sites, resulting in DMCA takedowns and search engine removals.
