tagging items as sold

Why do some people just edit an ad with "sold" instead of actually flagging it sold and taken it off the classifeds ...

Heck there is one in the solar that a guy posted another ad just to say the first one was sold... ohh well...

Well, what's worse in my opinion, is when the item is sold and they don't bother changing the ad or responding to those who inquire about it...
Recently,in looking for something, I responded to an old ad, got the message back that "yes, I still have it and it's for sale." "Great!" thought I...then proceeded to send multiple emails, PM's and responses to the ad only to have the dude vanish without a word. And the ad is still there... :S
