Welcome!
I actually don't know about Weku but Steemit has no such rewards so far. As you might have noticed, account creation currently requires patience and - due to the small amount of initial ressource credits (RC) - some investment to the platform if you don't get a delegation soon to be as active as you need to be in the first weeks to get a network of people reading and responding to your articles or videos.
Please monitor your RC at https://steemd.com/@build5-casole to avoid being unable to post or vote.
