What happens to harassing messages on Telegram?

What are the penalties for sending harassing messages on Telegram?

If you send harassing messages in a long-term private chat and are reported for harassment (report spam), or if you make inappropriate remarks in a public group and are deleted by the group administrator and report harassment (report spam), your account will be banned. Including not being able to speak in public groups, and not being able to take the initiative to privately chat with others. The first ban will be unbanned within a period of time. With the increase of the number of times, the subsequent ban will be longer and longer, and eventually your account will be permanently banned and cannot be unblocked.

As shown in the figure, this kind of prompt means that your account has been permanently banned, and this mobile phone number has also been officially blocked. According to the official TG statement: even if you delete and re-register your account, it is useless.
