Instant Checkmate is not illegal in and of itself. However, there are concerns about how the company collects and uses personal information. Instant Checkmate collects information from various public records, including court records, arrest records, social media profiles, and other online databases. This information is then used to create detailed background reports on individuals. Some people argue that Instant Checkmate's business model is unethical because it profits from selling people's personal information. Others say that the company provides a valuable service by making information about people more accessible. Overall, there is no clear consensus on whether Instant Checkmate is a legitimate or ethical business. It is up to each individual to decide whether or not they believe that Instant Checkmate is a company they want to support.
