Campaign targeting contry, but ads showing in other countries websites

Content network overrides your country settings?

I target a specific country and languaje in my campaign. When I don't include content network is ok. Ads are shown in google local. When I do my ads appear in sites from mexico and spain for instance. I didn't include those countries at all in my campaign. I just specified other LA county.
That's very annoying since those clicks are really garbage. How do I fix that?
Or should I just quit "content network"?

Could be based on IP address, so a person could have a site targeted to another country/language but hosted in a different country.

Just a thought.

I guess somebody from the country I'm targeting is visiting a website from another country and that triggers the ad. It't just that I'm surprised about how many mexican sites appear when targeting other la countries.
