I don't think that filling out a complaint with the SEC can be very useful. Ubiatar is a European company, based in Switzerland. Even if the SEC usually, when required, carries out its actions all over the world, if I remember correctly this ICO wasn't opened to American investors.
If we as bounty hunters want to report to the regulator, maybe is better to report the fact to the:
1. FINMA - Swiss Financial Market Supervisory Authority
This is the main site:

This is the main site:
https://www.esma.europa.eu/on the upper right there is the link to the page: "file a complaint":

In this section you will find information about complaints against financial market participants, other than credit rating agencies and trade repositories.
ADVICE ON HOW TO COMPLAIN ABOUT AN INDIVIDUAL FIRM
You have the right to complain if you are not happy about a financial product or service you buy from a firm authorised by a national regulator in the European Union (EU).
Without prejudice to your right of access to the judicial system, firms are required to have procedures in place to deal with your complaint. Some problems are straightforward and quick to solve. Others may be more complicated and, depending on the type of complaint, may take longer to evaluate.
But let's see before what happens since they have yet to start distribution for the content creation bounty and the translation one. And especially for the articles and blogs one, there are bloggers and small or big influencers who have taken part to the bounty: and if they are angry for the reward, they surely can delete the articles they have written about Ubiatar in the first place, and then write a new article explaining how they had been scammed in this bounty! It would not be a good advertising for them I imagine
By the way, they told us that the distribution is still going on, so I hope the mess will be fixed!
