Honestly, don't have the best relationship with LiA05 but her idea getting flagged as a scam or people not wanting to enter because they think they'll LOSE more than they gain is pretty stupid. Here are some things to consider before you shamelessly put down someone who's trying to actually have fun with a unique event while giving to the community:

1.) You are not obligated to enter, so quit putting down the host.
2.) 1 gift for a chance (albeit maybe small percentage?) to win $15. Here's why it may be a loss, but a very small one at that. For the effort of less than one Pyrat quest of gralats (700), you are getting over 53 times your input IFF you win. So yes it is a gamble as all raffles are, but considering your net gain if you win, this one isn't such a bad gamble when you lose so little.
3.) Why are the 10 gift options even being brought up? That's not for everyone clearly, so using that as a way to boost your argument to putting her down is kind of pathetic. The 10 gifts are just there to make the event more interesting.
