Recently, we found spamming issues associated with the view counts on a small number of videos. The inflated view count number on these videos will be frozen until actual views catch up to the published, artificial, view count. Also, a few people have commented that their view counts are updating more slowly. Occasionally the speed with which views update changes -- sometimes it’s faster and sometimes it’s slower. But we are always working to make sure that the final view count numbers are an accurate reflection of the community's interest.
