While discussing this we should take into account that information does not only leak from FT to other sites but also comes in from other sites.
I for myself transfered information from another comparably small forum to FT when I've seen that it also made it to third party sites. I got loads of good and bad feedback. My rationale was to spread the word on FT while it lasted to allow FT to profit from the deal.

I just wanted to point this out as it wasn't brought up from my point of view.
