Yes I think it would be a very simple solution (well, not VERY simple but doable) to put a moderator in place, that would make sure to only allow programs with at least a bit of transparency - and if it's clearly a ponzi, it would be mandatory to put a huge ass disclaimer, link to wiki and all that shit, that explains all the associated risks (this should just be in top of the section, in that warning message, clearly people don't think that it's enough).
Nope, I support it.
I was a newbie then and I got scammed here.
Eventually I find it about 99.9% thread here are all scam.
Well here's where you're wrong. They are only about 80-95% scam. The rest are legit, or at least at first.. which is how you make money if you have some brains.
If it's a hard fact that 99% of projects posted here are scam, then the bitcointalk admins are clearly doing a disservice to the community by allowing for it, and should shut it down permanently. Of course, as I explained, I'm not of that opinion.
There is one fully legit program in this subsection that I used for over a month, got to know the admin a little bit too - straightforward guy, one of few that disclose his source of income, (tip: not new deposits..); it's here:
