Good point

The ghost of a nerd died in 1998 adding animated gifs to your website while you sleep.

- Said nerd and I are probably the same age. I could live with this.
Your brand new laptop or whatever future devices they'll have in 2050 just stops working because of all the advertising spam in everything
- writing prompt; a small family keeps finding their futuristic computers infected with old malware. No matter how often they delete LimeWire someone adds it back.

The reason old buildings are "haunted" is usually carbon monoxide. That's why modern buildings don't have ghosts.

I just read a post-it about that...
- in my own handwriting no less
I think it can also have to do with pipes and stuff vibrating at a sub-audible frequency which can cause feelings of dread and fear. Horror movies use this technique pretty frequently.
- It also depends on people who believe in ghosts. A normal person just hears pipes making noise.
  I went to my buddies house one day and he was excited to show me a video he recorded.... of particles of dust being lit up by the cameras light. I almost felt bad to say the truth because he was so excited to have captured 'ghosts'.

I already fill that role in my household.

It probably takes a century or so for a ghost to manifest.

In the time span of eternity, 100 years is nothing.

It’s a lot of paperwork they have to fill out first. Permits and inspections. The bureaucracy of the afterlife.
- Luckily there's a handbook, though I've heard it reads like a VCR manual.

They haunt the abandoned malls and apartment buildings rather than old houses...

The show ghosts has a ghost that died in the early 2000s and he is just a baller "the pantsless ghost of a wealthy Wall Street stockbroker from the early 2000s" and he just wants to party

T Money!
When is the new season? September?
- Oh man, you just made me look it up, and now I realise there are way more seasons than the two available on my localized netflix 😵‍💫
  and it seems like season 5(!) is set for October, so I got some months to binge it all 🤩

"Get PWNT Noob" is written in blood on the walls. A classic late 90s haunting.

I'd totally buy a haunted mansion if it's haunted by a ghost from the 1990s. Hell yeah.

...Oh, I can imagine more headlines. Someone spending a lot of money to buy a house haunted by a communist, and the sociopolitical debate this purchase creates.

The causes might be environmental.
Haunted houses are a product of the US culture and the oldest houses commonly in use there are from the 1700s.
But it also needs to be fairly isolated - nobody is going to notice a haunting in the middle of a city.

"Haunted houses are a product of US culture", right...
There are plenty of haunting stories that predate the US by several thousands of years.

I would immediately find an exorcist to banish that bitch.

I'm pretty sure my ghost is still partying with the goths, in the loft I lived in in 2010.

If you start seeing phantom CD cases with lines of speed racked up on them, or hearing the faint sound of epic mashups, you'll know you're in the right loft.
