If someone at an IT company put down web admin for a moderate forum of ~500 users of which a 100 are weekly active users, serving a small CDN distributed over America and Europe (because side project not because logical), I’d be impressed a hundred fold over a Discord admin.
At best you’d be very good community manager/admin if you maintained and kept the server clean of a >1000 user server of which 500 are participating daily. At worst the interviewers would ask you why you’d maintain a kids voice channel.
Also putting out a forum on a resumee is more impressive (assuming the topics are something you’d want to share).
