There is no "shadowbanning" on Warpcast. 

If you make a top-level cast, it will show up in the feeds of everyone who follows you. 

You don't have to take my word for it. Cast something, take a friends phone and scroll to the bottom of their feed. Your cast will show up at some point - it will be higher up if they interact with you a lot, and lower down if they don't.
