In telegram you can have channels in which millions can receive massages instantly. Then you have the strong API to create bots do anything. One could be a bot to imitate anything published to a (source) channel through your (destination) channel. There has been a really good job done by aahnik for an automation bot that forward (or resend) any massage sent to a telegram channel. You can find the repo here.

Any thing the source channel publishes would be sent to destination channel. but there is something i want to add to it. if the source channel sent a reply to its previously published massage then the massage is sent as a new massage not a reply . i want it to be a reply (telethon reply method).
