Blocking entire countries in competitive filter

Can you block entire domain classes with Adsense competitive filter?

I was noticing in the competitive adfilter that you can leave off the leading 'www' and it'll still deny the parent domain (ie, foobar.com will still block www.foobar.com) - so I thought "Hrmmm... wonder if I can deny the entire country", so now I'm trying to block "com.{countrycode}"

Anyone tried this before? Does it really work?

The reason why I want to block an entire country is because I don't want targeted adverts from my own country appearing, since I am also a shop in the same market (locally), however since the site is viewed internationally the other viewers should be fine.

You can not block TLDs (e.g. .com) - this will result in an error message.

If it's not a TLD, e.g. in the UK where you have .co.uk, this should work ok.

I have been thinking about blocking TLDs myself, e.g. .info or .biz, but in general you have to be very careful about blocking TLDs. There is a good chance that you wreck a whole lot of valid advertisers.

If you block ".com.au" (as an example), that'll fail, but if you make it "com.au" it works (note the lack of the leading '.' dot.

I'll see how it goes over the next 24 hours. That's definately how my Adsense life goes, day at a time :D
