Checkdomain only provides detection and monitoring services. Any behavior that users engage in using checkdomain detection does not represent the will and opinions of checkdomain detection, and has nothing to do with the position of checkdomain detection.

It is strictly forbidden for users to use checkdomain to detect any illegal and criminal acts or help network information crimes. The users are responsible for the related responsibilities, and the illegal use will inevitably be blocked.
