I joined this site Zen Zuu. Do anyone know if it is a scam?

I think you should know how to checking whether a site is legit or not already. Some comments above are good and you may try them. I myself never heard about this site before. But if a site is legit and many people received payment from them then you can easily find some evidence about the legitimacy. However, a paid social site usually ask for more effort from us in order to be able to earn more money from such site. Have a nice day and happy mylotting.
