A post in Telegram is not always one message. Different attachments are built differently, and how a cloner handles them decides whether your channel looks tidy.
Albums
A post with several photographs arrives as several messages sharing a group marker. Naive handling publishes each separately, and an album of five pictures becomes five consecutive posts. The reader sees spam although the source published one thing.
Correct handling waits for the whole group and publishes it as one album. That is the most common difference between a homemade cloner and a working one.
Video and round messages
Round video messages are a separate type and only look right in your channel if you use the format yourself. Large videos take longer than text: expect a gap between the source publishing and your copy appearing.
Polls
A poll is not text with a picture but a separate object with votes. A copied poll starts from zero and lives its own life; comparing its results with the source is meaningless.
What to do with what does not copy
Simply do not copy it. A filter by attachment type saves you from posts that would look wrong anyway — what not to copy.
About formatting
Bold, italics and links are a separate story: they live beside the text rather than in it, and they slide when the text is edited — why formatting gets lost.
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.
