Every single entertainer (YouTuber, Twitch Streamer, etc.), community game server, some Open Source projects, Indie game developers and anyone who gets public support through Patreon uses Discord as the sole public hub. Colleges, Universities, Online courses also rely heavily on Discord. It’s a social network they can advertise, some servers are for subscribers only and is seen as a reward to get access to that. I’m part of a dozen or so servers for online things of interest to me, even though I hate the platform. It’s all silenced and without notifications, else I would go crazy, and I never chat with anyone there. But unfortunately there are several events, opportunities and activities that are exclusively communicated via the Discord server. It’s like cancer. Just like Instagram and WhatsApp, I have them not because I like it, but because if I remove them entirely or too aggressively it will take my social life with it.
