FAQ: checking Telegram channels for fake engagement
Answers about the cleanliness index, ERR, bot subscribers, manipulated views, evidence limits, and advertising due diligence.
Can fake engagement be proven from outside a channel?
No. External services only see public metrics, so the conclusion is probabilistic. Multiple independent anomalies can support a high-risk assessment, but they do not prove intent.
Does low ERR always mean fake subscribers?
No. A real audience can become inactive after a rebrand, a long pause, or a change in topic. Read ERR together with growth, reactions, comments, and the age of the channel.
What is the cost of choosing the wrong channel?
Potentially the entire placement budget. Automated or inactive accounts do not become customers, so checking the channel is usually the cheapest part of the campaign.
Can the initial check be automated?
Yes. TG Inspector collects public metrics and returns a cleanliness index, ERR, risk signals, and an advertising-reach estimate when enough data is available. Manual due diligence should still follow for large buys.
Why are bot subscribers dangerous for advertisers?
They consume budget without producing clicks, leads, or sales. The cost per real customer can become far higher than the advertised channel price suggests.
Can anyone report an exact number of bots?
Not from public data. External analysis estimates risk from reach and behavioral inconsistencies; it cannot inspect every subscriber account.
Why do channel owners manipulate views?
Artificial views can hide an inactive subscriber base and make advertising inventory appear more valuable than the real reachable audience supports.
Are forwards into private chats reliable evidence?
Forward counters can also be influenced and private destinations cannot be verified externally. Public reposts with visible active audiences provide stronger evidence.
Is high ERR always better than more subscribers?
Reach is generally more relevant to an advertiser, but it still needs to be credible and matched to the right audience. High ERR alone does not guarantee conversions.
Can ERR be too high?
Yes. Repeated reach near or above the full subscriber base, especially with flat counts and little activity, can be a manipulation signal.
Why buy views after buying subscribers?
Purchased subscribers create low reach. Artificial views can be added to hide that gap and support a higher advertising price.
What is the channel cleanliness index?
The 0–100 cleanliness index combines independent public-data signals such as ERR, view distribution, view accumulation, reactions, comments, and channel metadata. A higher index means fewer observed warning signals.
How do I check a Telegram channel for fake engagement?
Open @TG_InspectorBot and send an @username or t.me link. The bot collects a fresh public snapshot and returns the cleanliness index, ERR, risk signals, and an advertising outlook.
Can public analysis prove manipulation?
No. Only public metrics are available externally, so every assessment is probabilistic. Several independent anomalies can support a high-risk conclusion, but they do not prove intent.
What is ERR in Telegram?
ERR is median post views divided by subscribers. It estimates the share of the listed audience reached by a typical mature post.
How much does a channel check cost?
The first check is free and includes the full report. Further checks use one credit; multi-check packages reduce the price per channel.
