According to the search results, Zoro.to was a free website that streamed and watched anime series online, which was illegal. It was the worlds largest pirate site and had a lot of traffic. However, it suddenly disappeared and redirected to a new domain, Aniwatch.to, which was acquired by a new development team. The new site has a new look and feel, but the transition is seamless via a redirect, and old logins appear to work on the new domain. The sites basic user interface is the same as the last one, and the only difference is that the colors are different. The Zoro.to team assured users that all the data would remain the same, and the old staff would continue supporting the server. The reason for the rebranding is not clear, but it is speculated that it might have moved to a new domain because of copyright issues.
