But Billy Bartolomeus Tamawiwy, 22, entered pleas of not guilty in the ACT Magistrates Court on Tuesday to stalking, committing an act of indecency, and two counts of using a carriage service to harass.

During the appearance, Tamawiwy was also charged with another count of using a carriage service to harass. He did not enter a plea.

The Belconnen student has previously pleaded not guilty to two charges of sexual intercourse without consent.

Tamawiwy - an Indonesian studying in the ACT - is facing a total of 13 charges over his alleged online activities in August.

Court documents say he is accused of setting up a fake Facebook profile in the name of Tayla Edwards, using pictures of women he found on the internet.

He then allegedly sent a friend request to a teenage boy, who accepted despite not knowing a Tayla Edwards, and the pair traded messages.

Police allege their messages became sexual and Tayla Edwards told him she was bisexual, and wanted to have sex with him, but only if he had sex with another man.

The teen initially refused but was then allegedly enticed into having sex with a man by promises of free drinks, cannabis, and sex with Tayla Edwards.

Tamawiwy allegedly set up a meeting between himself and the young man.

The defendant is accused of filming the sex.

The teen later discovered Tamawiwy had allegedly controlled the Tayla Edwards accounts.

The teen contacted police after his younger brother received a Facebook message from Tayla Edwards that contained two videos.

The defendant is also accused of sending the videos to other young Canberrans before his arrest in September.

Tamawiwy will reappear in court in November.
