Everyone should be careful about participating in this bounty. While I am not saying anything negative about the project itself but looks like the bounty management team that this project has hired are a bunch of scammers who have stolen Bitcointalk forum's members personal information such as BTT username, profile link and the bounty managing people are submitting our details without our consent. If we look at the spreadsheet of Facebook and Twitter campaigns then we can see that since 11:26 AM, Thursday, August 29, 2019 (GMT+3) and up until now in just 2 hours there are about 540 people joined in the fb and twitter campaigns, averaging 4.5 Bounty hunters signing up in every minute!! 
And I see even my BTT details without my own MEW address on the fb sheet too at 121 number!
