He has also been convicted of sharing more than 25 terabytes of copyrighted data.
From March 2022 to May 2023, the man known as "KlammereFyr" on Reddit posted sexually explicit scenes featuring over 100 actresses.
He shared them in the subreddit - or forum - he was a moderator of.
According to the Danish anti-piracy group The Rights Alliance (TRA), his subreddit had more than 6,000 members and users were encouraged to request for clips of specific actors.
In 2023, campaigners reported the case to the police on behalf of the affected actors, directors and producers, which led to the subreddit being closed down.
Andrea Vagn Jensen, one of the actresses whose explicit scenes were shared in the group, told the Danish broadcaster DR at the time she felt there was a difference between appearing naked in a film and appearing on Reddit.
The actress said the posts amounted to "abuse".
