No offense, but this comes off as unjustly aggressive and unkind. A lot of the people who want Pokemon URLs and make “poor” offers are eager children who are desperate to have a URL of their favorite Pokemon.
You don’t teach people by negatively motivating them and being condescending. You teach them by being a nice person, having patience, and trying to understand their world view.
Remember: Once upon a time you were that 15 year old kid with a jumbled “put together” URL who was new to the whole URL-trading game and probably lived by the “If you don’t try, you won’t know” adage, too.
