If the firm discovers that the channel is breaking any regulations, it may ban the channel or restrict access to a public or private channel. It may also make specific channels unavailable for a brief period of time. Telegram, for example, can block a channel where copyrighted movies, web series, and other content is unlawfully exchanged.

Adult content and other sensitive items that promote hatred, violence, or sexual content are also prohibited. If you stumble across one, you'll get an error message that reads 'this channel cannot be viewed' or 'it's now offline.'
