Nobody is blaming you for closing the site (al least nobody with half a brain).
I cannot imagine what it would feel like to support and mantain a website for 10 years and that all the efforts are not appreciated.
What everyone is sad about, and probably they are expressing in a wrong way, is that all the knowledge and experience shared all over those years might be lost.
If you decide (by you I mean all unpack.cn admins) to save the data on the board, I (actually my brother) can make you a script to save all attachments or something like that.
One more thing, you say that 99% of people that only leech on don't share anything. I am going to defend that 99%, because I am one of them. Most of us don't have the knowlege to develop/discover something new. It is not that we don't want to share, it is just that we don't have the means.
What I really don't agree with is the people making money of others work.
I hope nobody feels offended with my comments, it is just my opinion
