There is an account security problem when purchasing the activation code. The activation code obtained from unknown sources or irregular channels may contain viruses or malware, resulting in the account being stolen or banned. In addition, criminals will also use the activation code for fraudulent activities to defraud accounts and passwords, endangering account security. The quality of the game is also a risk. Even if the activation code is normal, the corresponding game may have quality problems, such as incomplete content and serious bugs, which affect the game experience and even fail to run normally. In addition, the purchase of illegally obtained activation codes involves legal risks and may face legal responsibilities and penalties.
