Hi, Dexter, you have to be active only when you feel like it, there is no any obligation to upload though we are always happy to see your artistic work. Even though the main purpose of adding Steem rewards functionality was to reward BeScouted members with Steem we are aware that platform serves other multiple purposes too like casting and and showcase of portfolio hence we will be adding such an option so as veteran Steemit users that have uploaded most of their work to Steemit can choose if they want it to be cross posted to Steemit. As another temporary solution we can suggest disconnecting Steemit account from BeScouted in the settings and uploading as much work as you'd like without double posting it on the Steemit platform and then connecting it back when you wish. Hope this helps, cheers!
