From news release:
Surf2Web have implemented a FCTR (forced click thru rate). All this means
is that you have to click on between 1.5% & 5% of the ads you see to be
eligible for payment. If you do not meet this rate your account status will
be "inactive", This will not effect your money or points. Just at the end
of the month, instead of writing you a cheque we will leave your money in
your account to be paid when you reach the CTR.
