While she was 21, Khalifa made a total of 11 adult films during a three-month period, which she regrets ever making.
She also revealed on TikTok that the continued popularity of these videos often affects her mental health.
And every time she tries to have porn sites take down her videos, they decline and ignore her requests. Instead, she received death threats for the demands.
While she created the videos more than six years ago, these sites continue to 'promote her clips as though they're new.'
In a bid to assist her, Mia's fans created an online petition, calling for Pornhub and BangBros to remove her videos.
At the time of writing, more than 1.8 million people had signed the petition, titled 'Justice For Mia Khalifa.'
The petition on Change.org reads:
"The now 27-year-old Mia Khalifa appeared in the porn industry for a short span of 3 months."
"She [only received] $12K from the millions of dollars that Pornhub and BangBros make off her videos."
"The infamous hijab video has collected ISIS death threats that have targeted Mia from the video's release in 2014 to today."
"Mia [now] attends therapy for trauma, emotional distress, and consequences of bullying."
"We are demanding her domain names returned, her videos removed and fairly discussed in court without putting Mia Khalifa into deep financial ruin."
"Mia has stated her regret for her decisions in the porn industry multiple times."
Earlier this year, the Lebanese-American social media personality spoke out, urging girls not to join the 'toxic' industry.
"That hourly dissociative attack from remembering hundreds of millions of people's only impression of you is solely based on the lowest, most toxic three months of your life."
"I'm begging you not to. Not because I'm against sex work, I'm not!"
"I'm not going to tell you what to do with your body. But I am telling you to never let anyone have ownership of your content."
"Ethical porn exists. Support those sites, not the big production conglomerates."
"Those 11 videos will haunt me until I die. I don't want another girl to go through that - because no one should."
Mia also confirmed that she only earned $12,000 (£9,690) for her videos, which the streaming platforms continue to profit from.
And despite retiring from the profession more than six years ago, she remains one of the most searched actresses on porn sites.
