So what, that is how a ponzi works, no?
It is, and it is fundamentally untrustworthy to take part in or promote because of that.
So I am punished for playing the game how it's supposed to be played?
You're punished for promoting and condoning a service that is untrustworthy. It is irrelevant whether this is by design.
I am not condoning ponzis outside that forum
Irrelevant. You are condoning a ponzi, regardless of where on the forum it is.
If I were to go to a carding forum and say how great it was, would that mean I should be trusted? No.
I am not encouraging fradulent behaviour
Ponzis are fraudulent as they
will eventually steal from someone. That is a fact.
threads in that section are technically admitting to being a ponzi due to that is where they are posted, why would anyone not know it's a Ponzi if it's in the Ponzi section?
Because it isn't the 'Ponzi' board, it is the 'Investor-Based Games' board. Someone who is new to Bitcoin/doesn't understand English well may see a scheme there and believe it is legitimate. You saying 'this is great!' doesn't help this in any way, and further causes you to look untrustworthy.
