Hi @mahdiyari i had idea for steemfollower and i don't know if it has been suggested yet. But i wanted to share it just incase. I had the idea that you could do single post promotions rather than just the last post. Then disable the post @ 12 hours. Also make the user pay so much extra for this promotion. You could also make this its own tab. Just a thought. Thanks for everything you do your awesome!
