ProxyBlaster is right, you need to make sure your proxy has a TOS. If there was something more specific in the warning you will need to specify it here to get any useful advice.
Sorry but I cannot access orange1.info but my proxy is http://freeservers.mw I added a tos, anyone help me to check if the website is ok for adsense? Thanks.
Google Adsense Team only told me that they found my adsense was not allowed by their policy. orange1.info is an example they told me. And they told me that my websites should meet the quality that their webmaster guideline said.
I wrote a email to them and ask where should I improve my website but they replied that they don't know what exactly I should do but only told me to visit their webmaster guideline http://www.google.com/support/webmasters/bin/answer.py?answer=35769#quality
It appears Nicholas is correct. It sounds like they are growing weary of the "simple", contentless proxy sites. Actually, if this the case, the days of throwing up a quick proxy script page may be coming to an end, if your goal is to make revenue from Adsense.
Yes I do think so. So I have added something. Can you help me to check http://freeservers.mw, is that ok? I added some contect about proxy and also added a tos.
