A post copied whole often carries a link to the source channel, a mention of its author or a call to subscribe. Left in place, they do exactly what they were written for: take the reader there.
What usually gets stripped
- Links to the source channel and invitations to it.
- Mentions in the form @channel — clickable, same effect.
- «Subscribe» footers with someone else's address.
What to put instead
Nothing, or your own. Empty space at the end of a post beats someone else's call to action. Your own is fine if it is not under every post: a feed with the same line under every text reads as a broadcast.
The cost of editing
Any change in the middle of the text means the post goes out as plain text: formatting offsets after the edit point no longer line up — the mechanism.
Hence the practical trade-off: clean text without foreign links, or formatting. Both together only when the edit falls at the very end.
What not to do
Do not swap someone else's link for yours inside their text. A reader promised one thing who lands on another remembers it — and is right to. If you want your link there, put it on its own line in your own voice.
And about crediting the source
Whether to link back is not a technical question — cloning and copyright.
How Neurogram does this
Everything above is manual work that runs into the number of hours in a day. Neurogram does it on your own accounts and without you: it collects channels and audiences, writes comments and replies with a language model, and keeps limits and quiet hours so the accounts survive.
