Assessment summary

Infographics and study notes in Hindi for government exam preparation; the feed has been maintained for about four months.

Median views almost triple the subscriber count, yet reactions account for only 0.03% of views, with comments completely closed. Because of this imbalance, it is difficult to predict the actual ad reach.

What to pay attention to

More views than subscribers: ERR ≈ 293%

Median views are noticeably higher than the number of subscribers across half of the posts, not just for a single viral one. This happens when posts spread outside the channel via reposts, chats, or external traffic, but the other metrics do not support this version.

What grade F means

The index is at its lowest: the metrics fall far outside usual values, or Telegram has flagged the channel as a scam. See the “How the assessment was produced” section for details.

Compared with similar channels

Compared with 15 Education catalog channels whose metrics look normal. There are too few channels of a similar size, so the whole niche is used: 69 to 477,601 subscribers.

ERR (reach) higher than 15 of 15
@professorcockroach 292.6%
similar channels median 17.5%
Reactions per 100 views lower than 14 of 14
@professorcockroach 0.03
similar channels median 0.72

This is not a niche norm: only catalog channels are included. A high ERR is not always a plus: if the other metrics do not support it, the index goes down.

What scoring found in the view pattern

More views than subscribers: ERR ≈ 293%

Cleanliness-index history

The channel's data has been collected once — the chart will appear after the next update.

Advertising outlook

Advertising placement: not recommended.

Some of the channel's metrics deviate, so it is hard to say in advance how many people will see an ad.

Not calculated: many of the channel's metrics deviate, so a forecast would be unreliable.

Reach of advertising posts

No advertising posts among the latest 40.

Questions about @professorcockroach

What purity index was recorded for the channel?

The channel's purity index is 25 out of 100, which corresponds to grade F and the 'many anomalies' level. The score was reduced by abnormally high views against the backdrop of extremely low reader activity.

Why is the reach of posts significantly larger than the subscriber base?

With 1,336 subscribers, posts gain a median of 3,909 views, with the ERR reaching about 292.6%. At the same time, reactions account for only about 0.03% of views, and comments in the feed are disabled.

Is buying ads on this channel justified?

The feasibility of ad placement is flagged as questionable. Due to anomalies in view metrics, it is difficult to determine the actual audience of an ad post in advance.

Public Telegram data: posts, views, reactions, and channel metadata.
Date or snapshot
2026-10-03
Sample
The latest 40 public posts available at check time.
Calculation method
TG Inspector calculates metrics from the saved snapshot and combines independent signals into a deterministic 0–100 cleanliness index.
