You know, I'm going to take another angle.
Let's talk about proof and having evidence to back it up and accusations, shall we?
Let's pick a random comment out of this thread:

Here Raisor implies that if you post a message saying goodbye, it appears as though you are trying to get others to beg you to stay.
So we get a goodbye post. And instead of taking the poster at face value, we now have the suggestion that the post is not sincere, that it is only an attempt at garnering sympathy.
Does Raisor have proof of this? Is there a link? Should he be admonished for violating the message board's mission statement of posting things he only has proof of? Is he degrading the conversation? Is he accusing, without proof, posters who type goodbye notes of not being sincere and then personally attacking their character by suggesting that they are liars and only trying to get others to feel sorry for them?
Or, could he be privately considering all the possibilities and then posting one that he might think it is?
