On Telegram channel marketplaces, a channel with 100,000 subscribers lists for anywhere from $3,000 to $20,000. The seller sends screenshots of statistics, the numbers look solid. The problem is that inflating a channel by 30,000 bots costs about $10 and takes under an hour. You won't see that in a screenshot.
How channels get inflated before a sale
The standard playbook: a channel with 20,000 real subscribers gets boosted to 80,000 in the week before listing. Bots join quickly, and the subscriber chart shows a sharp spike. Reach stays the same — the 20,000 real readers are still there — but now they're 20 out of 80, not 20 out of 20. ERR drops from 30% to 7%, but over a few days that's easy to miss.
The subtler version uses offer-based accounts — real people paid small amounts to join. They drift off over the following months, and some delete their accounts entirely. By the time the channel hits the market, it shows 60,000 subscribers with 15,000 deleted profiles buried in the list. Invisible without a scan.
Three numbers that actually matter
TGuard scans a channel's subscribers and generates a certificate with concrete figures: a cleanness score (graded A+ through E), plus separate counts for bots, ghost accounts, and deleted profiles. Here's what each one tells you in practice.
Deleted accounts are the most reliable signal. A channel with organic growth will have 1–3% — people who left Telegram or got banned. If it's 10% or more, the channel either bought offer-based subscribers in the past or took a bot attack that Telegram later cleaned up. Either way, that's not organic growth.
Bots — accounts with no avatar, no history, no activity. More than 5% warrants an explanation before you pay. Sometimes it's a competitor attack rather than intentional inflation, but that doesn't make the audience any more valuable.
Cleanness score is the summary. A+ and A mean the channel is clean. B+ is acceptable — small losses happen in any channel. Below B, you need to understand why before committing.
Request the report before transferring money, not after. Generating it takes a minute, and an honest seller has no reason to refuse.
How to request the report from the seller
Ask the seller to add @channel_guardian_bot as an administrator, run a subscriber scan, and generate the cleanness certificate. The first scan takes a few hours as the data accumulates. After that, the certificate generates in one click and can be forwarded directly to you.
If the seller says they don't have TGuard, offer to let them add the bot themselves. If they refuse to grant even temporary access for an audit — that's a signal. Selling a channel doesn't require giving away the account; giving a bot temporary admin rights for a scan is completely standard.
If the seller won't provide any verification, walk away. An honest seller wants to prove their audience is real. Refusing means there's something to hide.
Red flags beyond the report
Check the subscriber growth chart in Telegram Statistics. A sharp spike over a few days with no obvious cause — no viral post, no mention in a large channel — is almost always inflation. Organic growth looks different: a gradual climb or clear peaks tied to specific posts.
ERR below 2% on a supposedly active channel is another marker. For channels under 50,000 subscribers, a normal engagement rate starts around 10%. If reach is near zero but subscriber count is high, the audience is dead regardless of what the certificate says.
What to do after the purchase
Once you take ownership, add TGuard and run a full scan yourself. The antivirus will start checking new subscribers in real time. If the scan reveals old inflation the pre-sale report didn't capture, the selective cleanup tool lets you remove subscribers by join date or account type without touching your real audience.
Frequently Asked Questions
Ask the seller to generate a cleanness certificate through TGuard. The report shows the cleanness score, bot count, ghost accounts, and deleted profiles. A high deleted account count is the clearest sign of past inflation.
The share of real, active accounts among all scanned subscribers, 0–100%, graded A+ (≥90%) through E (below 40%). A channel with no inflation history typically scores B+ or higher.
Red flag. An honest seller benefits from proving their audience is real. A refusal means there's something to hide — make the report a condition of the deal or walk away.
