Not really. A lot of the content that’s available for streaming on 4anime and sites like it is hosted and posted there without license or authorization from the production companies or artists who created said anime.
What’s more, the sites that host these shows that make it so easy to search and watch the titles for anime fans across the globe monetize content that doesn’t belong to them.
In short, they’re basically pirating shows, movies, and series that don’t belong to them, and in many cases, profit off of the banner ads and pop-ups on those websites.
While the amount of money is usually nominal (if you’ve ever used a streaming site, how many of those ads have you intentionally clicked on?) it’s usually just enough to help keep the site running by covering hosting fees.
