Is it illegal to send yellow MMS?

The communication company will randomly search for sensitive words in all short messages. If you are searched once or twice, you will be fine. However, if it is searched many times in a short period of time, the number of citations may not be 100, and it will be forced to turn off the SMS function, which is not illegal. However, if more people send text messages and accuse you of harassment, they should be judged according to the content, quantity and frequency of text messages. Take care of yourself. By the way, if a large amount of reactionary information appears in the short message and is detected, all your information input and output will be monitored by the security department, and the consequences are unknown.
