My name and information appear on porn sites all over Google search results

Explanation of complaint

Hello,my personal name and information appear on Google search results on various porn sites linking them to porn videos. 
More than 3 years ago my name was associated with 2 porn videos that were posted by a person that was trying to ruin my reputation and were  linked on more than 20 porn sites. I've asked most of the webmasters to turn them down form their sites because the videos weren't mine and they were doing a lot of damage on my reputation and career choices because I was found in many situations when looking for a job and my name was googled and I was rejected. Google search results link my name after the videos were taken down.Please help me resolve this issue
