I just submitted a speedrun for Geometry Dash Meltdown and the moderator does not appear to be active on this site, e=what do I do if this is the case? (Which it is)

Well they don't have a social media, and I kind of want to say that I'm the best in the world at something, and have some evidence of course, any suggestions?

This is the thread. Maybe post on the game forums?
