I have a suggestion : create a Ponzi section and not allow newbies to create a post in this section, it will mean that only bitcointalk members that have been here for a while can post and create a new ponzi, that will avoid a lot of chea.p scams
Ponzis are a gambling game, I don't think they are way more evil than regular gambling if the owner is not luring people into thinking it is an investment and if he is not running away with the money.
If ponzi section will be created and newbies and jr members will be not allowd to post there then there are going to be no ponzi at all.
99, 9% of ponzi threads are posted by users with activity <10.
:-)
There has been 1-3 ponzis that have been created by members, they didn't sc.am
Some of the ponzi owners will eventually get to the Jr status if they are dedicated, I am thinking about ponzicoin, ponzi120 and ponzimatic so it will just eliminate most the sc.ams and a lot of uninteresting ponzis
