What ADR3-N said regarding Geometry Dash. Blame all the folks in the GD community who have spammed the Audio Portal with stolen music. Here's a good point of reference, straight from RobTop: http://robtopgames.com/blog/2017/02/01/geometry-dash-newgrounds/
Try submitting more music if you're hoping to get noticed. As a rule of thumb, I never scout anyone without a decent repertoire of tracks. Five or more is a decent start.
And yeah, don't ask to be scouted. That's pushy, kind of pathetic, and totally against the rules.

Thanks to people abusing GD, no new artists can get featured in GD without contacting RobTop directly. If you're legitimate you will have a hard time, but it you're not, it will be impossible. Just some things to keep in mind. Also, asking to be scouted is a quick way to get banned from the portal.
