The online college account has been frozen, and some or all functions of the account have been restricted.

The account is frozen for the following reasons and the solutions are as follows: 1. When the account has abnormal operation and is suspected of being stolen, the system will freeze the account to prevent the situation from expanding. If this is the case, please immediately kill the virus, change the password, and then provide evidence to the relevant parties to complain. 2. When the user's operation violates relevant regulations, the account will also be frozen. If this is the case, users need to study the relevant regulations, delete the illegal content, wait for the lifting of the ban, and stop illegal operations in the future.
