Discord is excellent for cybersecurity community engagement and informal collaboration — that is what it is for. The defensive consideration is recognising that consumer-grade infrastructure with consumer-grade reliability is fine for social/community uses but not appropriate as the sole communication channel for time-critical coordination. Active incident response, scheduled CTF participation, time-bounded engagements — all need backup channels documented and pre-established. The work to set this up (backup Signal group, phone bridge, alternative Slack workspace) is one afternoon; the cost of improvising "what do we use?" mid-incident is much higher.
