All networks basically replace your AdSense with their 'claim' button. So that protection they speak of isn't unique to their network.
Also I know all networks have to start somewhere (these guys are a sub-network under Forela Digital), but I just read their about page: and given they all go by nicknames, I'm guessing they're all very young and probably know nothing about truly running a network (it's a business, you should have real names, real phone numbers and real people to contact)
These are the contract terms: if you disagree with anything, you may just want to wait. You won't earn any money if your channel is tiny so you may as well wait, as Zaph said.
70/30 split for two years is awful, too.
