Assessment summary

A channel about fan art and comics based on the webtoon School Bus Graveyard: character drawings, mini-comics with translation, and short author notes about student life.

A post is seen by about half of the subscribers — ERR 49.6% versus the median 18% for similar channels in the catalog, and reactions are unusually high: 8.45% of views versus 1.17% for the group. At the same time, the channel is dormant: the last publication was 40 days ago, and placement is marked as questionable for this very reason.

About the channel

The channel collects fan art and comics based on the webtoon School Bus Graveyard: character drawings, short drawn stories, and author notes about student life. It has been run in Russian for more than two and a half years; almost all posts are images, occasionally videos.

In the catalog, @iweriel and @mediyca are nearby: the first is roughly twice as large by subscribers, the second is a show-business channel with a million-strong audience. This channel is smaller than both, but a post here is seen by a larger share of subscribers than on @mediyca.

What it publishes:

  • Fan art: drawings of webtoon characters, often with captions and artists' watermarks.
  • Mini-comics: short drawn scenes, some with translation by the admin.
  • Author notes: greetings, good-morning wishes, and stories about student daily life.

Posts come out more often in the morning and afternoon, mostly on weekdays; there are no reposts from other channels or ads in the sample. By subscriber count, the channel is in the bottom third of the “Leisure and Entertainment” niche. The feed is dormant: the last publication was 40 days ago.

By subscribers, it ranks #15 of 20 channels in the Art & Design niche of the catalog.

What grade A+ means

The metrics agree with each other: views and reactions are distributed as usual, and almost no signals lower the index.

Compared with similar channels

Compared with 15 Art & Design catalog channels whose metrics look normal. There are too few channels of a similar size, so the whole niche is used: 40 to 164,812 subscribers.

ERR (reach) lower than 9 of 15
@shoolbu 49.6%
similar channels median 79.8%
Reactions per 100 views higher than 11 of 15
@shoolbu 8.45
similar channels median 3.17

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.

How the assessment was produced

Data source
Public Telegram data: posts, views, reactions, and channel metadata.
Date or snapshot
2026-10-19
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.
Factual result
The @shoolbu assessment dated 2026-10-19 uses 40 recent public posts. At that snapshot the channel had 256 subscribers, median post views were 127, ERR was 49.6%, and the cleanliness index was 100/100.
Limitations
This is a probabilistic assessment based on public data: it describes metrics, not the owner's actions, and is not a real-time measurement.
