At last Adsmacro.com came out as a fake site too??. Review on Adsmacro

Recently I have joined Adsmacro.com which is a free to join website, a data entry task website. its fun to complete the tasks and copy and paste the data in the given boxes.

Its nice to receive mails that "you are the task winner" and "you earned this much amount" no matter how small amount it is.

I completed several data entry(copy paste tasks) for which it is showing 1645 INR in my website earning bar.

when I read the withdrawal terms an conditions its was written that I should earn 1000Rs to withdraw, when I earned more than 1000 Rs through tasks, I tried to withdraw the 1000Rs but when I reached actual payment gateway, then it shows that I must have 3000 INR in my account to withdraw via paypal, Bank account.

I have also written a complain to support team on the support page of Adsmacro.com, but it seems to have no use writing complains, because no reply from the other end.

My Question are,

is this a real earning website or just another scam with no joining fee?,

why do they do this with people like me or you?,

whats the benefit for them? will I get the reply from this perticular website or ill end up with this site just like I ended up with other scam sites?

Is there anybody who is actually earning through this website or people like me just join like users and then leave the site when they get to know they cant get their earning whatever they do?

Ill appreciate if you can answer even one of my questions.

Hope to get my earning soon or at least get my issue solved with the site.
