First of all i want to say i don't consider this project is a typical scam.
My claim is that the team is trying to escape their obligations to bounty hunters.
My example: during bounty campaign i have earned 5400 und tokens via twitter campaign.
1 week ago I received 200 und tokens on my wallet. When i tried to ask in their telegram group, why so little, my question was deleted.
And i am not only one. Many hunters received 50-200 und tokens instead amount in the spreadsheet.

Ok. I tried to use this form (link to form was on bounty thread). But I have not received a reply.
Then i tried to ask in telegram group, why the team didn't respond. My message was deleted.
Then ceo of UND said: "lots of stuff was chopped down by our bounty squad from the original award because of low quality after it was reviewed and reconsiled. "
It was after a lot of people asked why they received so little amount of tokens.

And the most unpleasant is why I created this topic:
- spreadsheet has been operatively hidden after this situation.
- bounty topic with all information in first message has been changed. (https://bitcointalk.org/index.php?topic=5072910.0 see 1 message)
- form for bounty question has been deleted too.
It is unfortunate that such a promising project as it used to be, uses deception of its community members and bounty hunters.
But the amount of bounty payments is tiny. Can you trust such a project?..
If you are participant of this campaign, I ask you to write here as well.
Sorry for my english, its not my native language.
