No, in both directions.
We don't buy advertising or media. If you're offering to promote the app on your channel for a fee, we won't be taking it up.
There's no way to advertise inside EQUALS. We don't sell placements and there's no ad product for brands.
If you're an artist wanting to reach people here, you already can — your chatroom and the feed exist for exactly that, and they reach your audience directly.
