We agree. My point was that people get and follow internet advice, ie. "flush your freehub", don't understand the implications, and end up worse off than before.
I often post based not on what I would do, but what I expect a less knowledgeable person to do. After all, if they were more knowledgeable they might not have asked in the first place.
