i don't know whether the proxy is allowed in adsense TOS..

but Yes this traffic is enough to put adsense...
i think add adsense gadget in the place of recent post and place 300 x 250
if the size is not fit means, edit the width and insert the gadget...

because in 300 x 250 google will place mostly flash or image banner, possibly it attract more visitor to click..may be

good luck

Note:
don't even think to click your own adsense , even in dream, then you will get banned email after getting up
