Nearly 50,000 people take part in Anders Högström's adventures on Facebook. But one day, Anders noticed that a clip had received an unusual amount of attention.
"I got a handful of Arabic comments on one clip. It was a bit strange, I think, since the site is mostly in Swedish, but I didn't think more about it and went to bed, he says.
When he woke up the next morning, the clip had exploded.
"There were upwards of 400 comments, many of which were very crude. Both from Palestinians and Israelis," he says.
The clip has then been picked out and re-edited and started to spread in social media, where it is claimed that instead of a Swedish bunker from the Cold War, it shows Hamas' secret tunnel system under Gaza.
Watch the clip to hear how Anders Högström reacted when his clip was hijacked for propaganda purposes.
