Banuddar, it will infact discourage people to post bugs, but only the people that really shouldn't be posting bugs. The way I look at it, if you and I post a bug, it's fine, we have an IQ over a 100. This 'threat' is for people who honestly post bugs that we can't even comprehend, 'my characters foots hurt from walking to far, can i get a port' or something ridiculous.
Though it is a cocky state of mind, I find that confidence never hurt anything. Almost always, if there is a reprecusion it's just motivation for the people that are good at it, to do better, and maybe filter out a couple of people who can't handle it.
