How to earn from reality networks site?

I registered with this site three month back..But still I can't understand anything in this site..Even I don't like to understand, because of their emails...Our up line members are contacting us and asking us to invest in the sites(mostly, they are not our up line member, might be the site person)..I used to avoid the mails..I forgot the site..Then mails started to reach my in box, from my " down line" members. asking us the earning procedure in the site and the procedure to invest(?) in that site.I, my self don't know my referral line of that site, till date..then I don't know how members are registering in our down line..Probably scam site..

I don't about the site. But I have seen a payment proof if that site.
