There have been a number of achievements removed.
Some that were broken and the KotH related ones as well..
From the support tool:
We have indeed removed several achievements that were not unlocking automatically when the task was completed. In many cases, the task could not be completed in the current state of the website.
The achievements that have been removed are the following:
3D Glasses
Man vs. Machine
Second Opinion
Hindsight 20/20
Statistician
Buddy System
Social Butterfly
Dangerous Intersection
Those achievements do not exist anymore.
