Gaming Discord servers grow fastest through post-video engagement. Dropping a "behind the scenes" clip in Discord within 1hr of upload drives 3–5× more comments. Game Night events convert lurkers to active members at a 15–20% rate. Doosk, BingSchnapper, and Milliepex going live in Discord voice during a Game Night pulls in members who'd never interact otherwise — make them regulars, not lurkers.
