I never quite understood the point of these support forums. I’ve spent decades with in tech and I don’t even remember one instance when these forums have been useful. One phenomenon that is interesting is that there are always people with 15000 messages, some wierd titles like “approved”, “community gold member”, “not an employee of x” etc always with a signature “If I helped you click on thank you button” that spew absolute useless, no effort advice or ask crazy follow up questions that have nothing to do with the problem. What is the motivation of these people, what do they get out of this?
