Kitely's service page, right above the Create New Account button states:
"
Create Your Free Account and Get a Free World
Create your free account now, and get a FREE 1-region virtual world!
That Metered World will use your account's Free Regions quota so will
remain available for access indefinitely. We'll also give you 6 free
hours in-world to try out your world. You don't need to give us your
billing information to get this free trial period, so act now and you'll
be able to start building your world within minutes."
The terms are clearly stated upfront, there is no bait and switch here.
