We are a US based company that ships only to US and Canada. We've had two issues arise recently from foreign countries (Russia namely) that caused us to block access to our site from anyone attempting to interact with our store from outside of the US and Canada. 1. The first issue we encountered were fraudulent orders originating from Russia (using stolen card data) and then shipping to a US based International shipping aggregator. 2. The second issue was a consistent flow of Russian based "new customer" entries. My question to the MOZ community is this: are their any unintended consequences, from an SEO perspective, to blocking the viewing of our store from certain countries.
