Yes, "drive by" and "one and done" posters are a PITA. Especially when you actually spend some time to help them find an answer, and you don't even know if they ever came by and read the fruits of your work.
A certain active poster started a big rant and many chimed in with their opinions, some agreeing with the OP and some not, and the OP NEVER EVER replied back in his own thread. Either to defend his original rant or to modify it or ANYTHING. It is the equivalent of driving by with submachine gun and spraying the area, never to return. I would suppose he "got off" by stirring up a big old pot of "stuff" and laughed all the way home. That is all I can figure.
