I was asked for my opinion of this thread.
> Someone give you negative trust for participating in a PONZI?
How would anyone even know that you participated in a ponzi? Just play the game if you want to - it's your money and you can give it to a scammer if you like.
I suspect that you received negative trust for promoting the ponzi, not for participating in it. Posting on the forum about how you played the game and made a profit isn't just playing the game, it's promoting the game to others, even though you know it's a scam. You're free to do that if you like, and others are free to leave you feedback drawing attention to how you are promoting a scam.
It looks like this is one instance where Dooglus declares "do as I say, not as I do"
In late 2014, dooglus publicly (claimed to) invest in, publicly played at with very large amounts, gave positive trust to (claiming to have risked 100 BTC), and was a moderator at with his "Dooglus" handle at a site that was very new and had little reason to be trusted with thousands of BTC. The site turned out to be a scam and even after it was revealed this site was a scam Dooglus still promoted the site by proclaiming that it was not certain the site was a scam. This site just so happened to scam their users just a day after Dooglus was able to withdraw all the BTC he (claimed to have) invested at the site. All this was after he had made over 50 BTC between gambling winnings and bankroll profits (if I remember the amount correctly).
Shortly after this incident, he endorsed another site with his signature that outright turned off their servers and ran away with over 2,000 BTC, but again not before Dooglus was able to withdraw all his BTC (and of course profits).
Dooglus was doing much more then telling people about his experience, he was actively telling people to invest and deposit into these scam sites and was getting paid large amounts to do so. The OP in this case is merely telling others about his experience and even warned about a potential danger of the site.
I wonder if devil is going to leave negative trust for people who post about large wins at Just-Dice since Just-Dice is run by a scammer.
