Is SMOG Coin scam?

There are a few websites like cryptolinks and scamadvisor that claim the SMOG Cryptocurrency to be a scam coin. Does anybody here have any information about this?

To be honest their whitepaper is a joke? It is only 1 page long. And I get very suspicious when the website is telling me that I have to stake for 90 days and according to a fresh post on reddit you are not able to see anywhere your staked amount of SMOG. This seems to be fishy in my eyes. But on the market it seems to be a so far successful coin?
