A 21-year-old Maple Ridge man read an apology letter to his victim during his sentencing hearing in Port Coquitlam provincial court last week.
"I did not realize the power (social media) held until it was used irresponsibly... Just a few clicks and it changed your life and how the world viewed the person that you are," Warrington said about posting photos to Facebook of her engaged in sex acts at a party in Pitt Meadows two years ago.
He called his actions "thoughtless and supremely immature" and said he will always regret what he did.
In the early morning hours of Sept. 11, 2010, a 16-year-old boy took eight photos and a video of two people engaged in sex acts at an outdoor rave in Pitt Meadows.
The complainant said the sex acts were not consensual.
"Your actions actually ruined my life," the 18year-old woman told Warrington in court, sobbing. "Dennis, you destroyed the person that I used to be." Warrington was initially charged with publishing and distributing child pornography.
However, in December he pleaded guilty to distributing obscene matter.
The judge is scheduled to deliver her sentencing decision March 4.
