Okay, complete shot-in-the-dark prediction here - I expect Newgrounds is gonna see an influx of musicians from this.
I am admittedly biased on this (I'm heavily active on there), but I do have precedent to point to - Tumblr's NSFW ban in late 2018 led to a minor influx of artists in November, followed by a site-crashing influx in December, after the ban was officially announced.
