Why there is viglink link on site i visit?

[sapta]

Few days ago i visited viglink . com just curious what kind this site is. Recently, when i visit some sites there are some viglink link on its text content !, i don't see viglink script in html source code.
I found answer for this, we have to go to viglink website and click the opt-out link.

How come this happened ? I never opt-in for viglink ads!
