有种是被判CA的。只能通过发邮件。尝试让telegram恢复。但目前是无果的。没有希望的。

还有一种是现在常见的

This group has been temporarily suspended to give its moderators time to clean up after users who posted illegal pornographic content. We will reopen the group as soon as it complies with the Telegram Terms of Service again.

/unblock_group你群UID@AbuseNotifications

有可能需要删除所有内容才能恢复
