I was already able to fix it. I saw the announcement on RCI's telegram regarding the bounty. You should close the option to send new links. Also, it will not be fair for those who submit their work if it will not be counted. The effort was not easy.
Why? We have started a week ago, there are plenty of tokens to be distributed. I have added this to Bounty FAQ:
Tokens, not stakes? Yes, you will receive equal rewards for your activity despite total number of participants in certain program.
This is a great difference with stakes model, where each new participant decreases reward. However, participants that join later will receive less or even nothing if the program cap has been reached already.
This intended to be a stimulus to participate in bounty and not to wait until the end.
