Mr Jackson believes the orbs are part of a millennia-old Earth defence system, and poltergeist activity is some sort of side-effect, or perhaps a way of keeping people away from the locations of orb operations- one of three types of spheres described by Mr Jackson reside in (presumably 'normal') buildings. They operate 5-10 miles (approx. 8-16 km) apart from each other, so we must conclude that orb and poltergeist activity is being seriously under-reported.
...Mr Jackson – an IT database specialist – says he honed his skills on trying to understand poltergeist activity in a famous location – 30 East Drive, home to the most 'aggressive poltergeist' in the UK.
"I observed silver spheres flying around the house, tennis ball sized drones, intelligently controlled.
"Like marbles bouncing off the walls, hitting my face.
Unfortunately I don't think Mr Jackson managed to capture any footage of these events, which must be very frustrating for him seeing as he'd gone there specifically to investigate strange activity.
Luckily, we can visit 30 East Drive, "home of the most aggressive poltergeist in the UK", in Pontefract, West Yorkshire for an overnight stay at just £85 (just over $104) so it's pretty certain that someone will be able to confirm Patrick's observations,

The house itself is a fairly standard-looking 1950's semi-detached, so the Earth defence spheres obviously took up residence sometime since then, maybe while the owners were at work or out shopping.
Personally, if a mysterious high-tech planetary defence system started hitting me in the face, and I realised it was acting intelligently, I'd re-evaluate some of my beliefs, but maybe Mr Jackson is more stoical. Or maybe he can't take a hint. ;)
Edited to add: If Mr Jackson's belief that poltergeist activity is a mechanism to deter people from investigating orb operations, the sale of tickets to visit 30 East Drive demonstrates that this tactic is failing.
