Looks like a break down in semantics but I think a ponzi scheme can be seen as a gamble.

Gamble:
: to risk losing (something valuable or important) in order to do or achieve something


If I invest in a ponzi scheme I am risking that I will get money back,risk vs. reward!
But I hate breaking this down because ponzi schemes are more clear cut on the taking advantage of people.
I am not putting people through the ringer with negative ratings over this so I can choose to be passive in the relationship of the words.
Think if you are going after ponzi schemes the logic extends to gambling as well. But thats splitting hairs.

My issue stays the same. If you choose to pass the warning on the subforum,its all on you after that point. No need to waste time chasing down ghosts that are just going to reappear in a weeks time.

**Edit***
Negative ratings also keep people out of signature campaigns,so this is not just a warning to other members. It has a stigma.
