I have previously asked questions and read about the importance of always using a new address every-time you receive a transaction, even for change. Sometimes when I watch the block explorer I see transactions where the send address and change address are the same, like this one:
It is also my understanding that most wallet software automatically generates a new address for change. This leads me to believe that the transactions where the change address is the same might be people using more advanced wallet software that gives them more control over these features. Are there known reasons or types of users who intentionally choose not to follow the advice to use new change addresses?
