How and who would you handle this Internet situation...?

[Chris]

If you realized or suspected your internet activities were on a private network of some sort or restricted and redirected to only certain types of websites or webpages, (similar to parental controls or net nanny web browsers. But you are NOT a minor, have a guardian, or have given anyone permission to access your computer in order to do this.) who would you contact to ask, complain, or have it investigated and how would you prove or explain your concerns or suspicions?
