Will this block every other country in the world except the ones i’ve listed? Or have i understood this wrong?
Yes it will block all others. However, you may be blocking search engines too.
Alright. But i don’t want search engines snooping either… I have another rule to block bots.
Just for reasons of simplicity, the “is not in” operator might be better for your use case.
Alrighty, even better. thanks
