I agree with you , I tried one which is advertised on this website it is just a waste of time , people joined there keep sending you messages to get 1 MLC all the day getting notification and meaningless message. also what I find that it is owned by a person who is trying to gather people on his website .it is just a waste of time answering same questions , some of them were happy as it turned to be a chat and earning for chat. and what earning 1 MLC for each post boring.
also I think that website is not legit and it is a scam.
