Member counts are read from the group’s own public profile page — the same t.me/<name>surface a channel’s count is read from, printed in full rather than short-formed. See how we measure.

Growth

6 measurements spanning 16 days, net +12. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 4,011–4,027 and does not start at zero.

A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the member count as measured 23 August 2026 — this entry's latest reading, not the date you are reading this.
