You probably have more people contributing on Discord than you'd have just on Github. Maybe 2, 3 or more times as many.
Discord tends to be social in a way Github is not, with lower friction to contribute. And perhaps even a better asynchronous model.
I don't discount your frustrations. Maybe a bot that can create GH issues from Discord would help. With rights to use it spread liberally around the community.
Tell people you need help getting data into Github, give them a bot so they don't have to context switch, and they'll probably surprise you.
