I asked a question in their telegram group, but they deleted it.
I also wrote to the project team DATABLOCKCHAIN.IO and they promised to consider my little investigation.
It seems that the moderators do not have time to keep track of such topics or they do not care?
I've taken a look at candyman22 post history (
https://bitcointalk.org/index.php?action=profile;u=1289445;sa=showPosts). It seems he's just a sockpuppet account created for this bounty. He got a nearly full stake for every campaign, certainly suspicious. He's not online after May 9th, but somehow he got a full stake for at least 10 weeks campaign (assuming it started from May 8th, it is impossible for him to get that stakes).
You can view the registration spreadsheets I gave above for each category (Twitter / FB / articles / signature ) these bots were not even registered in the bounty campaign... Accordingly, they cannot receive stakes at all...
Obviously, in such a case, the one who gave them the stakes is their owner and the scammer.
