Gamblers with Debt is not new. Many of Gamblers (Addict Gamblers) had debts. I personally experienced that long time ago when I'm addicted to a dice game. I borrow some BTC for my friend in exchange for my salary for a month. I lose multiple times and wasted my 2 months salary just on playing Dice. I remember PD was the Dice site where I lose money. 
As I've said, Gamblers with Debts is normal.
I dont know why i feel that these online casinos are surely rigged. Think yourself why you loosing money after sometime ? I bet that whenever you tries to stake up you will be busted surely dont you think that this is not a rigged poker ?.As I've said, Gamblers with Debts is normal.
I remember that in 2013 when the game called head tail was popular with liberty reserve money, Someone came to me by saying that he have script to setup such site where he told me that there is a option to set difficulty level for players which means you can set difficulty level to high to make players loss. I am 100% confident that those tactics still exists with these dice casinos or gambling sites.
