I am one of the participants of this project campaign (twitter, facebook, medium and reddit). Of all the tasks I did, they did not pay anything to me. BAD BOUNTY CAMPAIGN !.
Sad to hear it. I think not only you, besides you are still a lot of unpaid REDBUX campaign participants. Only a few people and that too with very little rewards. Skip this project bro, because there are still many other projects that are better than this scam project.
Their ITO was ended for months and no updates yet. Their Social media channels dead, no news, no updates, no active admin on Telegram. If the number show in their website is truth so it means that they gained around 33M EUR via ITO. If they are coming to scam, this is the biggest scam ever in ICO world.
