A channel list is not a one-off job. It begins to rot the day it is collected: channels close, stop publishing, turn comments off. Within a couple of months a noticeable share of the list is useless while you keep spending attention on it.
Four ways a channel dies
- It stopped publishing. The obvious case, and the easiest to detect.
- Comments were switched off. The channel is alive and useless to you if you work through comments.
- It changed subject. Still active, no longer yours — the most annoying kind, because no automatic check catches it.
- It was deleted or made private. Gone entirely.
What to check
Date of the last post, whether a discussion group is attached, and views relative to subscribers. That third figure separates a quiet channel from an inflated one — spotting a fake channel.
Subscriber count on its own tells you almost nothing: it is the number that decays slowest and lies most.
How often
People lists age slowly, channel lists quickly. Monthly is a reasonable rhythm for channels; before each campaign is right for people — cleaning a database.
What to do with the dead ones
Remove them from the working set but keep the record, or the next collection run will find them again and you will re-check the same corpses every month.
Why this is not optional
The size of the live list caps everything downstream: how many accounts you can usefully run, and how much any of them produce — how many channels you need.
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.
