manipulation currently has over 700 0 questions. Its excerpt:
Manipulation is the act of algorithmically manipulating any pieces of data
...is ambiguous and not helpful, in my opinion.
Interestingly, questions that have this tag are often trying to spell something manipulation.
Feed the roomba by downvoting useless questions: https://stackoverflow.com/search?q=%5Bmanipulation%5D+answers%3A0+score%3A0..
manipulation adds little information to the questions. Request to burninate the tag.
Note: I noticed from the Suggested Edits review queue that, someone keeps editing questions (over a hundred) to remove manipulation but never fixes other problems in these questions, please improve the questions with all the problems, questions with ambiguous tag often have a below average quality.
