Since one month we have had unusual results in the pageview statistics of the German Wikipedia. A moderately well-known musician and two of his projects are high in the Top 10, which is not really comprehensible: [[de:Tobias Sammet]], [[de:Avantasia]], [[de:Edguy]]
This is likely to be a bot-based manipulation. The statistics are displayed in the mobile apps, so you could promote something in this way.
The articles cound be excluded from the statistics, perhaps there are also countermeasures that directly affect those bots,. Alternatively, the display of the most frequently viewed articles could also be removed from the APP in order to combat this manipulation.
