Is it a sentence to send unhealthy information through QQ?

This generally depends on the situation. Sending unhealthy information through QQ is definitely illegal. If the circumstances are serious, it is suspected of committing a crime, because it is different from enjoying yourself on your own computer. Sending unhealthy information and establishing a yellow QQ group are suspected of spreading obscene articles (referring to the act of spreading obscene books, periodicals, films, videos, tapes, pictures or other obscene articles in society for profit, and the circumstances are serious). Please refer to (Article 364th 1 of the Criminal Law) for specific punishment methods.
