Is rewardstoday.co.uk Safe?

WARNING: Beware of fake gift programs, promotions, surveys, rewards, coupon or other offers which appear to be to good to be true. As a general rule, sites which offer something seemingly substantial in return for very little, should always be approached with a great deal of skepticism. Stay away from sites such as this to avoid being victimized.

The competition might not be entirely above board, after all I was brought to this site through a get-paid-to-do-stuff site, and am therefore being paid to enter a competition... but how does giving out my name, postal address, phone number and date of birth immediately put me at risk of ID theft? I think cotojo is over-reacting a little.
