While I commend the folks at SN for taking steps to improve the service by implementing the online training module, with the goal of reducing the amount of pernicious, inadequate or otherwise flawed reports that are submitted to the NWS, I don't believe you can ever realistically eliminate the problem altogether.
With more and more people becoming aware of and utilizing the service, this is bound to happen on occasion. I personally believe that the training module has reduced the amount of downright asinine reports that were becoming more frequent until the training module was implemented. However, you're always going to have people who ace a test without walking away with any true, working knowledge of how to apply the material that they were tested over to real scenarios.
