Basically..because of Massive Abuse..
fixing lotteries, rigging results, scamming, major profit to the lottery holder which just basically translates to people taking advantage of other people's clintz..etc etc..
here are some reasons if you want to have a look at why it was decided to ban lotteries:
But there are good lotteries.
The essence of lotteries are the chance of winning a big prize for a small amount of money.
And the holder of lottery allways have a small profit.
"Real world"s lotteries are the same: small entry fee, big prize.
And admin can check lotteries so i dont know why have to close all the lotteries.
some example for good lotteries:
A ban is a ban..may it be good or bad or anything in between..all of it must go..we don't play favorites here and let a lottery be held by a player while others can't hold their own..
just imagine this situation for a second..
someone holds a very big lottery (let's say 500 tickets involved and hundreds of thousands of clintz too), of course we can't check all the players involved every now and then with the number of lotteries around specially if the lottery holder doesn't give us all the info..then at the end of it all, we bust it as a scam, imagine if this happened a couple of times per week, what more, lots of times..imagine how many angry players will protest, how many we need to resolve, how much time it will take to attend to one lottery problem..how much flood messages we'll get from angry players..etc etc..
"prevention is better than cure"
it's better that we just don't have it and avoid problems, than to have it and encounter such problems and abuses..
Force Majeure raises an excellent point. It is a shame to see lotteries go though.The good ones are there but lotteries can be rigged so easily. For example, lottery holder takes money. Awards a partner the card as the prize. Partner gives back holder's card, then they split the money. It would be so hard to keep track of lottery scams.
