This number sent out a text to my cell phone (I NEVER give my cell phone number on any contest forms I fill out). Text says:

"Your entry from last month has WON! Go to < website address > on YlaD and enter your Winning Code:   < 4 digit number > to claim your FREE $500 Target Giftcard!"

I'm thinking that website is nicely infected with some virus or trojan.... I'm very sure I never entered any contest where this was a potential prize.

This is a scam. If you get a similar text to this, don't go to the website.
