The fact that you participate in so many bounties in such a small amount of time indicates to me that you are posting absolutely garbage content. I guarantee you get awarded minimum stakes every week for doing exactly this, possibly even no stakes at all if the rules are strict. If I were a bounty manager I would block all spammy accounts from participating, as that doesn't generate any awareness for the project at all.
My goal is to earn money. If managers blocked accounts with spam. Then I would not have participated in this campaign with this Twitter account
