1000 subscribers in a week... riiiight. It took him forever to hit 110,000.
And what has he done to earn that? Two videos in two weeks and the one about Norway is still languishing at a sad 12K views in 2 days.
I call bullshit.
This is just a lack of understanding on how YouTube publicly reports subscriber counts. At certain thresholds, it only updates the count every 1k subscribers. So, for example, one could be sitting at 101k subscribers for years while subscribers trickle in and out. Once the count adds up to 102k, then YouTube updates the public facing subscriber count.
