Before, view-checking mechanisms worked differently than they do now. Up to 300 views, a simple condition was used for the counter to work.
After that, an advanced verification algorithm was connected and repeated views were filtered out.
Because that a simple condition statement was used before 300 views, the counter of some videos got stuck on the number 301.
For example, this video: — 1.1 million likes.
— 18,000 dislikes.— 165 thousand comments.
— And only 301 views.
Now this bug does not exist. YouTube algorithms from 0 views work in the “correct” mode, cutting off duplicate and fake views.
