Are there most viewed writers in every topic on Quora?

Patrick Ehlert’s answer to What determines whether a Quora topic has a “Most viewed writers” statistic associated with it?

As Patrick Ehlert has pointed out, some very popular topics are blocked from having MVW:

• How Much Does X Cost? (2.1K questions, 2.5K followers)
• Survey Question (253.5K questions, 28.4K followers)
• Quora Community (29.7K questions, 10.9K followers)
• Best of X (58.6K questions, 112.2K followers)

I remember seeing somewhere that “adult” topics don’t have MVW lists either. Nothing in Pornography or Porn Stars, for instance.
