It took me a lot of time to participate in the bonus campaign, I worked hard, writing day by day, when the project announced the bonus campaign ended, and sadly I knew that they scammed everyone, right? When I was disappointed that I wasted too much time, I lost a lot of money to the bonus campaign, they demanded too much but never paid for me. Everyone who has fallen into the same situation ?
It's unfortunate what you had to face but really there is nothing you can do about it because since its declared scam, it means you have worked for free. Really that bounty sphere of the forum needs to be sanitised but the fault from my end is on you the participants by not ensuring basic things are in place as you get blinded by the returns promised and several others would have been banned for breaking forum rules while trying to meet up with the requirements of the campaign.
Something basic as ensuring that whatever the payment you were promised is already secured with escrow. In the past, even funds raised was kept in the hands of escrow to ensure distribution is made to the right party in due time.
