Blocking or retrieving information about forwarding bot's messages

[kapisolec]

Hi, I was thinking, is there a way to block users from forwarding telegram bot messages or retrieving information about forwarded messages of the bot?

See protect_content in send* methods: https://core.telegram.org/bots/api#sendmessage

ctx.sendMessage("Protected reply", { protected_content: true });

Setting protect_content to true can prevent messages from being forwarded and saved. However, if the owner creates a discuss group which link to this channel, the message will also be able to forward to the discuss group, the then messages can be forwarded from discuss group. How to prevent this happens? Thanks

Just a hole on Telegram's side. Nothing we can do except unlink and have the bot post in both places if needed.
