Ren, who was 19 at the time, filmed himself in early 2017 replacing the cream inside the biscuits with toothpaste after being challenged by one of his 1.2 million followers to carry out the prank.
He gave them to the homeless man outside a supermarket, along with €20. The homeless man was identified only as Gheorge L., born in Romania and in his early 50s. He once worked as a shepherd before migrating to Barcelona, according to El País. The homeless man vomited after eating the biscuit.
After the posting of the video prompted widespread condemnation, Ren replaced it with one in which he visited the homeless man again and offered him another €20. According to police, he later offered €300 to the daughter of his victim in return for not filing a lawsuit.
In his defence, Ren said that the video was just a bad joke, for which he had later sought to make amends. "I do things to mount a show: People like what is morbid," he told the court, according to reports in the Spanish news media.
But the judge noted that Ren had earned more than €2000 from advertising revenues generated by the video, one of several he filmed in response to various challenges received from his followers.
"This was not an isolated act," Judge Rosa Aragonés concluded in her ruling. In other videos, Ren also displayed "cruel behaviours" towards "easy or vulnerable victims," the ruling added.
In the original video, which was later removed from YouTube, Ren acknowledged that he "may have gone a bit far," but added that there was "a positive side," saying: "This will help clean his teeth — I don't think he has cleaned them since he became poor."
