If it was undesireable, there would be no option to use it. If people offer their help, its up to the people that take them up on it to determine whether its a bait for service sales tactics. Asking people to stop volunteering their help for free is not a good idea in general. It mean's you're probably reading HN too much, and possibly on a screen that's too small. Just get used to clicking on the "More" button, it works! :P
