Last time I checked, the support forum was overrun with spam.
A few months back, Joesph sent an email saying that there is
problems with the capcha, but it usually kicks in after several
blog builds. At that stage, you give up for the day.

IMO, if you're hitting Google a lot of the time, they would probably
start to restrict how you use their services. Could that be the
reason you're not having any luck?
