ASP Anti-Malicious Registration Engine (ValidateClass) is a self-written APS class that prevents various types of robots from maliciously registering or publishing spam messages. It is simple and convenient to call. After use, you can cancel the verification code according to the situation. Unless the other party writes a robot program specifically for this algorithm or registers manually, registration is not allowed.
