Yet they still won't take non-US advertisers. Reddit claims "legal issues." In 12 years of buying online advertising from the US, I've never seen such a restriction before. What are they doing.. giving away free prescription drugs with every order?
I'm in Canada, and I didn't have any problems.
That said, it was a waste of $20, I didn't get any sales.
I brought up the US-only issue before on HN and a couple of people reported success using it from overseas. Yet someone from Reddit was incredulous and couldn't understand how that would work.. perhaps I should just try it ;-)
Yahoo Publisher Network, Facebook (for the first 6 months) and a few other networks have had US only policies, partly due to advertising restrictions (tobacco, pornography and such) but partly to handle the inventory and scaling.
