Digital Hoarders
There should be a Hoarders spinoff show called "Digital Hoarders," showcasing people who hoard their digital content - whether it's maxing out their Gmail, overrunning their desktops with old files, chaotic Downloads folders, excessive browser tabs, apps on their phones they seldom use, or even phone contacts including that one random guy named Mike Shapinko they met back in college at a house party that they've never spoken to again.
Things that, if it were in the physical world, they'd have gotten rid of long ago - but because it's digital, they'll hoard forever.
(Admittedly, I'm guilty of a few of these. I'll text you one day Mike Shapinko. One day.)
