It would have been helpful if you have provided more info on your website - not necessary to give the url - info on the contents. If I want to be dramatic too, I would be able able to provide interesting images of some Adsense ads being served at my 50+ websites and start asking what is that and what is this.
my site... www.arenagold.com Different language..,since my forum site using english as main language there.
Strange thing. I went to your website and have seen turkish. when i refreshed it i have seen english and then turkish again.
Geotargetting. It thinks you are from another country. Go here http://seomoz.org/ip2loc and see what it tells you where you are from (the default ip is the one it detects from you)
You may be right but not for his personal ip. I am in central Europe right now and i see both turkish and english in his site. probably it has something to do with your hosting package ip address Why don't you contact google?
i noticed some of your members in shoutbox and forum are talking in turkish about using proxies in US, maybe thats a clue?
If your site is hosted in a proxy it could possibly be the problem. Go here http://whois.domaintools.com/arenagold.com where, you can see the complete whois of your site. And then mail to google. By the way your IP points to Malaisya in http://www.seomoz.org/ip2loc That is my opinion Good luck
