could be some truth to what he saying about online casino's there why not, look at the large number of rogue site operating now, but I don't know who this guy is and how good his word is.
The problem is that his views seem to expand to "all Jews", not just "unethical management of some companies" are out to rip us all off.
It is the same view that throughout the ages lead to Jews being persecuted. They had the reputation of being "sinful" because they were often "money lenders", and many grew rich from this trade without ever doing any "real work". It's like bankers today, they would be persecuted if they didn't have the protection of their wealth, government, and their "old boys network". Bankers are also "money lenders", as well as "gamblers of other people's money", and have been the problem that almost brought an end to capitalist civilisation.
His views seem to be influenced by the fact that the Jewish state has revoked his right to travel back to the US from where he came, and keeps on going after him. His extreme views about his ex wife being "influenced by Satan" might offer an alternative theory as to why she divorced him. His is that the divorce is part of a conspiracy against men orchestrated by Satan and Jewish women.
His rant about online casinos doing dodgy deeds and ripping off customers looks pretty tame compared with the rest of those articles.
If he named these casinos, we would be better able to judge his claims. Oddly enough, despite how they have wronged him, and the whole Jewish state has conspired against him, he STILL wants to protect his former employers' reputation by keeping their identities secret. If he cared about people getting ripped off, he would offer up his view on which casinos the rest of us should avoid by naming and shaming all those casinos that lie and cheat, and pretend not to be run from Israel when they are.
Far more dangerous for players are those casinos run from places like Costa Rica and Panama.
Jackpot Factory casinos have been run from Israel since I first knew them, even though they were licensed in Kahnawake, and now Malta. Only fairly recently have some rather dodgy things been happening there, although they did get caught out doing some highly unethical marketing a while back. This is not good, but hardly constitutes a conspiracy to rip off players.
