Beware of My Mega Sale Voucher scam

I have received this email from mega-voucher@woldam.com, which states that I've won shopping vouchers worth RM 1000. 

The site is owned by Planet 49, which holds some fake contests.

The following blogs have posted on this scam too.

According to http://cintamenora.blogspot.com/2013/04/1malaysiavouchercom-satu-penipuan.html,

they will charge RM 5 for each question sent via SMS (this is how they cheat your money).

Google the contest website if you think that there's something fishy about the contest.

Beware of fake Reader's Digest sweepstakes

The email is sent by friends@emails.rdasia.com.my .

It will redirect you to https://www.rdedm.com/ASIA/my/061128101/page1.asp and ask you to activate your code.

I did click the link although I doubt that I have subscribed to Reader's Digest. It will ask for your information later.

There are several sites which said it's a scam.
