We've noticed on some of our sites that there seems to be a lot of international traffic. While it isn't necessarily harming our sites in any way, it does throw off our data reports. Most of the time it seems to happen as a large spike in a single day. Almost all of our sites are small, local (Maine) businesses, so international traffic doesn't really make sense anyway. For example, one of our sites, a local hardware store, has almost as many visits from Ukraine as it does from America.
Is there anything we can do about this? Blocking international IPs or something? Does it make sense to do anything about it?
