The 7 Red Flags
- ER below 1% — A channel with 50K subscribers getting under 500 views per post is statistically impossible with real audiences. Real audiences view 15–40% of posts.
- Subscriber spike of 5,000+ in 1–3 days — Without a visible viral post, major press coverage, or declared paid promotion, this is almost always purchased.
- Views flat while subscriber count grows — If views stay at 2,000/post while subscribers grew from 10K to 40K over 6 months, those 30K new subscribers are not reading.
- Geography mismatch — An English-language B2B channel showing growth from Southeast Asia or Central Africa is suspicious without explanation.
- No engagement increase during growth — Real subscriber surges bring more comments and forwards. A surge with zero engagement increase is bots.
- Telegram purge drops — Sharp subscriber drops of 2–10% with no announcement often reveal a prior purchase being cleaned by Telegram's bot detection.
- Unnaturally round milestone jumps — Growing from 9,980 to exactly 15,000 subscribers in a week without viral content is suspicious.
