First of all he's accusing me of promoting a ponzi scheme. I admit that i'm involved (as investor or gambler) in gambling and investor-based section games
Right, so you send money to ponzi scams in the hope that somebody further down the queue will get ripped off when it inevitably collapses. But not before some of their funds are sent you to as a reward for your collaboration with the scammers.
Because that is essentially what you are wanting to be paid with, a share taken from other people's money. The operators of these schemes are sharing the proceeds of theft with earlier participants. They are paying you for helping to keep their scam running.
This pretty much is the definition of somebody who is not trustworthy.
Think I'll contribute to the appraisal of your character, too.
