Its because its a fork of Ethereum made on Github platform. Elementreum is also a Ether fork so nothing scammy at all!!!
Please dont spread FUD that doesn't make any sense at all. If you do better research you will see its all legit.

As quoted from the CEO of Arabianchain Mr Mohammed Alsheli on Facebook:

"ArabianChain was not an ICO that's why it's a bit different as we didn't raise any funds from the community and we have investors who own an equity in ArabianChain Technology "the company" and not DBIX that we have to answer to. All the work you see here is part of our social responsibility and we do it because we are willingly supporting this project even though we have negligible financial gains from it. ArabianChain Technology is an innovation hub that provids business and technical counsaltancy services for governments and private sectors here in the region and that's why we are not as visible as other projects in social media channels because we cannot announce any of those projects until the designated entities decid to go public with it. That being said I really appreciate your thoughts and feedback and we always seek to improve so thank you for sharing and thank you for being part of this family."

Its possible, it can also be very small if no big news is coming....
