He didn't lost, the team stole his reward to the same wallet!
I have the same problem! LOOK HERE :
https://imgur.com/GOfoDCXA year ago I made a huge work for these guys, joined a lot of campaign, and recieved to my wallet 34386 coins MB8.
At the same day these coinds were transfered to the team wallet.
The team completely ignores my requirements, blocked me in social networks.
I know that you do not want to return to me my tokens that were taken back from my web wallet.
But I know what to do with such scammers!

Ill tell them frankly, Ive been in cryptocurrency for a long time, I know a lot of people, I have two community telegram channels of 1,500 people that are my friends, and I want to tell them that they can ask administrators of Redme, Repux.io (huge projects) , these companies lost all their investors because they did very stupid things with their bounty hunters. They had to pay a fee in full to us and all they lost everything. In MB8 case, I would recommend that they return guys funds to their accounts, otherwise I will be forced to write to my friends bloggers, telegram channels, and Bitcoinalk about how MB8 behave like thieves. We do not like scammers, return what we earned and do not need anything else. We have nothing to lose.
