Koh created a Mega account with his email address and used it to download sexually explicit material from the cloud through links he found on Sammyboy.
When police seized his phone during the arrest, they found 467 photos and eight videos depicting child sexual abuse.
The prosecution asked for 15 to 17 months’ jail, with Mr Chan stressing the lengthy period of offending.
He pointed out that Koh’s actions directly harmed the children depicted, and also caused wider harm by creating demand as a consumer of child sexual abuse material.
Mr Chan noted, however, that Koh downloaded the photos and videos for himself, and there was no evidence he distributed or profited from them.
Defence lawyer Danny Nah said Koh recognised his wrongdoing, underwent counselling, and had since turned to exercise and photography to curb his urges to view sexually explicit material.
In deliberating on the sentence, District Judge Paul Chan observed that the volume of illicit material found in Koh’s possession was among the highest seen in such cases.
Koh will start serving his sentence on Jun 12, after a deferment to settle personal matters. He remains out on bail of S$10,000.
