Next, the technical aspect: how do these sites operate? Are they legal? Probably not, since distributing pirated content is illegal. The ".net" or ".in" domain here is part of the URL, but the actual legality might depend on the source. The "upd" part could refer to updates on new releases or the latest news. So, the site might be providing pirated copies of Hindi movies dubbed or dubbed into Punjabi, and they update daily or weekly with new ones.
