The man, who lives outside of Varberg in southern Sweden, was sentenced to one year in prison for breaching copyright laws.
The 34-year-old ran a file-sharing site between 2007 and 2009, allowing users to illegally download copyrighted material, including movies, games and music, according to the Hallands Nyheter newspaper (HN).
He was convicted of aggravated accounting offences, acting as an accessory to copyright offences, and aggravated tax crimes, according to the Expressen newspaper.
The man made over 2,000 files available to the public and is alleged to have earned more than 1.5 million kronor ($209,553) without paying taxes, wrote HN.
However, as investigators were unable to pinpoint exactly how much the 34-year-old earned, the court denied the prosecutor's request for the man to be handed a 390,000 kronor fine.
On top of the Varberg district court's decision to sentence the man to one year in prison, he will be furthermore prohibited from running a business for three years upon release.
As the man uploaded the files for other people to download, and not for himself, the court has convicted him as an accomplice to the crime rather than as the perpetrator.
