Hello,i found some items on marketplace that i am interested to buy ,question is if thiese items are legal or not? ,presumed that if they are listed in marketplace sould be legal otherwise is a trap for those who use them.Thiese is just a few of them and they have one thing in common,like pay per play raffle,but marketplace is full of them.Is it legal or illegal to use them on your land? https://marketplace.secondlife.com/p/Raffle-Board-Raffle-Contest-Prize-Giver/2392504 https://marketplace.secondlife.com/p/Raffle-Board-V100-CopyBoxed/6309955 https://marketplace.secondlife.com/p/Raffle-Board/9221654 https://marketplace.secondlife.com/p/Laigon-Raffle-Board-boxed/2185915 https://marketplace.secondlife.com/p/Raffle-Board-Deluxe-no-copy-version-v2/1739870 https://marketplace.secondlife.com/p/RAFFLE-BOARD-V-11-2019/18302697
