Whoa man...keep the cool. You had some good reasons in the top half of your post, but I could tell you were letting your frustration take over your thoughts as the post went on. It's good to know that you have some conscience, unlike some of the other flat-out flamers, but just a tip. In a forum, the one with the most amount of reasons and examples to back up his/her opinion, yet also post with the least amount of emotion (usually anger), is the final winner.
I can understand your feelings towards K-Durant's actions, but it's always a good idea to keep your emotions in check, if you hope to have others understand and support your opinion.
All in all, though I am no moderator, there are definitely people on this forum with a little too much ego, and refuse to show any "soft spots", and here we have K-Durant in the spotlight. Sure, he doesn't like to show gratitude to contributors of the forum, and sure, he loves to criticize in nonconstructive manner. But in time, I believe that he will start to see the consequences caused by his own actions, and learn from them. Thus, I believe he should not be permanently banned from this forum, as he needs to
learn (by himself, and perhaps with some small help from the community

) to think before posting. And this is an important step in the maturation process.
But hey, nothing a little warning can't do, right?
