modern-day hoarder

Like a normal hoarder but with digital items instead of physical ones.

Somebody that saves all their emails from the beginning of time, or downloads movies never to be watched.

I pirated the entire Harry Potter collection but have no plans to read any of it. I am a modern-day hoarder.

Digital-hoarder

Collecting digital media for the sake of collecting it, not watching and/or listening to it. Accumulating titles that you have no interest in, no intent of using for entertainment and no desire to do anything with except just possessing it.

I downloaded the complete discography of Michael Buble because I'm a digital-hoarder.
