Engagement
20 posts held, back to 4 July 2020 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof 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 1 September 2022. An engagement rate over an empty window would be a number about nothing.

Pessoal, vou testar uma transmissão para inscritos através do discord. Estudei uma vulnerabilidade ontem e vou criar um profile para acha-la no Burp Bounty. Se você é inscrito, é só entrar no grupo do discord https://discord.gg/E4hgJwdP e integrar com a Twitch, que automaticamente vai entrar no grupo. Se não é inscrito e quiser participar, só se inscrever lá no Twitch. As lives gratuitas com os estudos continuam. Val…

Pessoal, ementa e calendário prontos. Só falta o conteúdo! :D Passando aqui para avisar que provavelmente irei liberar o link do curso aqui primeiro. Vai ser pela GoHacking, 24h de duração, divido em duas semanas. Nessa primeira turma nós limitamos o número de vagas. Sobe o conteúdo: Só vamos falar de Server Side e coisa atual.
Showing the 12 most recent of 20 posts we hold for @reefbr. 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.
