I keep seeing this posted over an over again by multiple people, but it makes no sense to me. I'm referring to the notion that me using the system a certain way has any effect your privacy. Like me re-using addresses has any effect on you. Could you explain how this is so? Its not a self-evident claim at all.
I can give you a simple example: say I don't reuse addresses and I send you a transaction. If both of us didn't reuse addresses then someone looking at the transaction wouldn't know how much I spent vs how much was change or other payment recipients. However if you reuse your address it would make it quite evident to external people that _your_ address is with a very high probability not the change and likely the other address used is my change.
