LinusCoin exchange. Heard of it???

I am in a group that trades on this exchange called LinusCoins. Every other day there are new tokens listed and the price goes up..and all the members in the group go gaga about the profits they have earned. People continue to put money into the exchange…and trade. Now – there is NO mention of a LinusCoins exchange..anywhere on the Net (except one press release !) !!! All the tokens that are listed on it..do not seem to be listed anywhere else. Is it even legit? I have asked if people if they have had luck withdrawing money….but..all of them have been pumping in money to see their numbers rise and are excited. Weird !
