There are many bloggers out there who were totally wiped out from Google Adsense because of using traffic exchange sites like Linkreferral. I too was wiped out years ago because of same reason.
As we know, Google is very keen when it comes to their TOS and in that TOS using traffic exchange program is strictly prohibited. They always make sure no one is cheating so they made this feature in Google Webmaster Tool that is pretty useful in our part as a blogger at the same time an advantage to Google. This feature is called "Links to your Site" which allows us to know if our site is being used by another site through links.
Example:
Once you link your site to Linkreferral, Google Webmaster Tool will automatically detect that in a few days if you are constantly receiving traffics from Linkreferral. Google is very much in control to all our Google accounts so they definitely know everything what’s in our Google accounts.
But whatever Google’s decision about using Linkreferral, lots of bloggers and site owners will keep using Linkreferral because of its ability to promote. You cannot just receive traffic from Linkreferral if you are not active in making reviews and comments to other sites which is what makes the site very popular. Comments and Reviews are the life line of our sites and blogs, without it, you are just wasting time and effort. Linkreferral might be a traffic exchange program if others thought about that way, but the important thing is that, it does not give you non-sense traffic or I call it “pass-by traffic” like auto surf or manual surf (easyhit4u, HitSafari, HitBooster, and etc.) does.
