A Colombian man Juan Sánchez Latorre who admitted defiling nearly 300 children has been sentenced to 60 years in prison.
A court in the city of Barranquilla observed that Mr. Sánchez Latorre committed the crimes in 2007 to 2008.
Sánchez, in his late 30s, used the alias Big Bad Wolf to share images and videos of the abuse online.
He was arrested in Venezuela a year ago with a fake identity card after five years on the run.
During the trial, Sánchez pleaded guilty to defiling 276 boys and girls.
Prosecutors said he had approached his victims online and then met them at shopping centres, offering them money in exchange for sexual contact.
If they refused, they were often attacked.
The authorities believe Latorre committed other crimes in Venezuela before being finally arrested in the city of Maracaibo and extradited to Colombia in September 2018.
His neighbours said they never suspected he could be a dangerous paedophile.
