Browsing through the questions on SO, I noticed the quartz tag and saw hundreds of questions that should be retagged. It is also mentioned in http://meta.stackexchange.com/questions/128315/the-great-stack-overflow-tag-question-cleanup-of-2012
What should be the proper way for replacing these tags, I found it a little bit disturbing editing the question and adding a "removed batch added xyz" type of comment.
Is this is a good behavior? I wonder if bulk updates of these kinds are welcomed by the community or they are seen as reputation hunting.
