Chris D'Elia has been accused of harassing underage girls online, with several women sharing stories of the comedian soliciting photos and asking them to meet up with him when they were teenagers.
The actor and comedian released a statement denying any predatory or unlawful activity, however he did apologise for being a "dumb guy" who got "caught up in his lifestyle".
"I have never knowingly pursued any underage women at any point," he said.
"I have never met or exchanged any inappropriate photos with the people who have tweeted about me."
A string of damning tweets about D'Elia's actions began with a thread by Twitter user Simone Rossi, who referenced his role as a pedophile in the Netflix thriller You.
Rossi included screenshots of email correspondence she allegedly had with D'Elia at the age of 16, in which he asked her to meet him after one of his live shows and requested pictures.
"Imagine being 16 and being groomed by a stand up comedian twice ur age and the only reason you never met up and never got physically (molested) was because u had just gotten a boyfriend ur own age [sic]," she tweeted.
"For the longest time I thought this was just a funny story to tell at parties when I realised what happened isn't normal and that he was and could still be doing this to younger girls and it's my job to say something."
D'elia, who also portrayed a pedophile in an episode of the comedy television series Workaholics, "promised to do better", saying he had been "reflecting" on his past despite denying any wrongdoing.
Rossi's Twitter revelation prompted a flurry of similar stories from other women, many of whom also claimed D'Elia had requested nude photos of them and asked them to visit him when he was touring.
One woman dubbed D'Elia "trash" claiming he asked her to go to his car and perform a sex act on him after putting her name on the doorlist at one of his shows.
Another shared screenshots of Facebook messages allegedly from a 30-year-old D'Elia in 2011, in which he persistently contacted her and asked for her phone number even after ascertaining she was 17.
While many of the accusations came directly from personal twitter accounts, a user with the handle @sheratesdogs began compiling anonymous stories from women who were afraid of backlash if they spoke out. Almost all of the accounts of sexual advances from D'Elia came from women who said they were in high school at the time.
Actor Maliabeth Johnson, who has had roles in Parks and Recreation and Mad Men, condemned D'Elia as a "predator" on Twitter, claiming she had turned down projects because of his involvement.
"100 percent f**k this guy," she wrote.
