Discord is one of the most used among gamers.
Many of my horny fans play the same video games as I.
One of the most entertaining things is being able to play against your favorite pornstars and win to get her naked on stream.
This wont really work without a service like discord that makes it easy to create servers to voice chat and share all kinds of relevant stuff while gaming cus gaming also has the "need to share the game rooms links/pass" "or debug config if something is wrong" also the server ownr has absolute control over who can or cant do what.

It's a must to be able to share Discord server invites
