I don't really get the mentality. The users know what they are posting isn't tech support but do it anyway. You see the same thing on deal sites like slickdeals/fatwallet where someone posts in the hot deals forum and even says something like "this isn't a hot deal but I wanted to get the most people to see this..."
It also happens in Amazon product reviews. I don't want to read about how the 3rd party merchant you ordered from took 4 weeks to ship it to you when I am looking for product (not merchant) reviews. All the people who give 1-star reviews to books that aren't available in Kindle format to 'force' the publishers to release them are doing the same thing. It's a self-entitlement problem.
