Yes, I was also participating in their bounty, and I remember myself that I had that strange feeling when I saw their posts always with such a strange pictures that was always one like another and thought - probably it is not good. So here we are. DNO = scam.
I wonder what you will do with the received DNO tokens, if you think this is fraud? Will you sell them or not? I think that there is no need to rush with such a statement. Time will tell whether this is fraud or not. I have repeatedly seen how for various trifles begin to write that some kind of project, this is fraud. Practically it happens in any project. However, I did not see here that anyone should complain about being deceived and not paid DNO tokens.
