You can check the history of the domain with the WHOIS lookup tool. WHOIS is a tool that provides the user with any information about a specific domain name. Anyone can access your domain information via a WHOIS search until and unless you buy domain privacy. Without privacy, one might face many dangerous threats that can eventually ruin all the time and effort.
All the reputable registrars are providing domain name privacy protection. For example, I'm a customer of AEserver and bought domain privacy. If someone tries to access my personal information, they will only get the information about AEserver. My information remains protected.
