Google Adsense Unverified Sites

Hello guys,

I just recently receive this warning on my Google Adsense Account.

In the past 7 days, your ad code has appeared a significant number of times on sites you don't own. To avoid lost revenue, make sure to add these sites to your verified sites list in My Sites

I do understand what this warning means but my question is that, what if a trusted website are the one displaying it like Google.com itself?

Here are some of the unverified sites that are displaying my ads:

google.com.eg
google.com.hk
google.com.mx
google.com.my
bing.com
translate.yandex.net
images.search.yahoo.com

Should I block them from displaying my adsense ads or allow them?
