Government is already forcing you to pay so many taxes, so why would they need to force you for doing that with lotteries? 
This scheme was invented as their extra passive income and additional voluntary tax.
If you dont see that that you are deluded.
Lol, so this is why it's a scam?
This is probably a conflict of how things work in different countries and some see tax on winnings as something extraordinary but it's not!
It has never been something weird in most of western world, you pay taxes for all your earnings! All!
You win a car in cereal box competition, guess what, if the promoter doesn't pay the taxes for you yore going to have to pay 10% or 19% of the value for the car as taxes, it's considered income. For two years I've been paying tax on my earnings from betfair, they only cover themselves up to 1000euros in tax the rest is your business, does that make them scam?
It's the same for casino, so , again here is the scam?
You buy a lottery ticket, you lose you lose, you win you get your price and you pay taxes.
Not knowing how it works it's not an excuse!
No, it's not a scam, I'm with Stompix on this one. What happens in the lottery is public and if people are fool enough to play a game that only returns between 50-70% of the prizes collected, as well as charging taxes if you win in some countries, that's your problem. And I include myself among the fools who play from time to time. I don't know if it is also said in English but in my language some people call the lottery the tax of fools or the tax of those who don't understand mathematics.
Yeah, it's pretty normal pooling together funds scheme.
I wonder what people thing on jackpots on all those gambling websites they advertise!
Oh, let's look at freebitcoin.in, they give you a lambo which of course comes from the tickets you bought and what a surprise
"If the winner wants the car in any other country, they will need to pay the excess shipping costs and any applicable taxes or fees"
So is it scamming you? Of course not!
