This is my first offer/request of this sort.
I have a high traffic proxy/proxy list/proxy FAQ site which receives 25,000 unique hits per month. China, Taiwan, Hong Kong, Iran and Nigeria are all blocked to filter out low-converting traffic. None of the traffic comes from proxy.org or other traffic generators. It is all a result of hard work.
I am willing to show traffic screenshots and the list of keywords/keyphrases from AWStats. I will also show that the site is in the top 10 Google SERPs for some great proxy-related keyphrases.
It also has high Alexa ranking and decent Google PR.
If anyone with 2 proxy related-sites (at least one with high traffic, and will show stats) wants to do a comparable 3-way link exchange, please PM me.
