5 measurements spanning 37 days, net -2. 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 121–124 and does not start at zero.

Engagement

20 posts held, back to 3 May 2026the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 7 July 2026. An engagement rate over an empty window would be a number about nothing.

Reaction mix

21 reactions across 13 posts, in 4 distinct kinds. The most used accounts for 38.1% of them.

Every reaction kind recorded on the sample, most used first

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 13 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 21 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 3 May 2026 to 7 July 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

🔐 ওয়েবসাইট নয়, এখন হ্যাকারদের প্রধান টার্গেট REST API। আজকের মোবাইল অ্যাপ, ওয়েব অ্যাপ ও SaaS প্ল্যাটফর্মের মূল ভিত্তিই হলো API। তাই API-তে থাকা একটি ছোট দুর্বলতাও বড় ধরনের ডেটা লিক বা অ্যাকাউন্ট টেকওভারের কারণ হতে পারে। ZeroDay Test এর ভালনারেবিলিটি ব্লগ সিরিজ এ এবার Topic - Understanding REST API Security: Why Modern Applications Depend on APIs 💢 Explore - https://zerodaytest.com/blog/understanding-rest-api-secur

Showing the 12 most recent of 20 posts we hold for @ZeroDayTest. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Forward network

Republished by

Channels on the register that have forwarded this channel's posts into their own feed.

Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
