AdWords Policy vs Site Security

I realize that this issue is not a problem with Wordfence per se. But may be relatable to other users of the Wordfence ‘country block’ feature that we use for our site.

Riddle me this…

Google has suspended the AdWords campaign for a site I manage. The backstory is:
– our Adwords is, and always has been, only set to target US Google searches.
– our site is only accessible to US IP addresses. We use the country block feature to block non-US traffic for 3 reasons:
1. We we only sell our products to US based customers.
2. We want to reduce the risk of our site being infected or tampered with by malicious overseas hackers.
3. We want to reduce the risk that our products will be copied and “knocked-off” by overseas companies that do not respect US copyright and trademark laws.

Google is now suspending our campaign and telling us the reason is that fact that our site is not accessible worldwide is a violation of their AdWords policy.

Again, we have had the non-US traffic block on our website for years now. Why all of a sudden would AdWords be forcing us to expose the site to the world just to run our AdWords in front of US based customers?

It seems absurd that we would have to open our site up to the world and raise our risk profile just so ads can continue to run in the US. What am I missing? Please advise. Thanks in advance.
