I had no idea the Italian Mafia used the resources and man power to hunt down lottery winners in their own villages and cities, which is frightening. If lottery operators are aware of those problems in their societies, then they should completely give the option to their winners so they can claim their jackpots anonimously. One can understand that the lottery, as a company, wants the public to know they are legitimate and they indeed pay to their big winners, but FORCING their winners to risk their physical integrity for money is simply utter selfishness and stupidity.
There could even be some link between the Italian Mafia and the lottery operators to carry out those crimes against winners, but I don't have any proof of such corruption, neither would dare to try to write much about it, for my own personal security, mafias and crime syndicates are not to be underestimated.
You understand how it works and I agree that there is a high possibility for this to be true and it would also explain why the lottery would make it a requirement (or did so in the past) for winners to come out in public. Because if they didn't get mentioned publicly, how would the mafia know who won the money? That would allow for the only conclusion that someone from the lottery operation is giving out names secretly.
Having a lot of money is amazing and solves so many problems, but it changes life in a different way and I think people who go from no money to millions in a short period of time often underestimate the true consequences of that. People who have been rich for a long time learned and know what to do, whom to trust and how to behave in certain situations.
