lemur - it's unclear from your post if by "we" you mean whether ePlaya will have them (or allow people to post them) or whether you mean we as in you or other users should plan and organize ticket raffles.
If you mean whether ePlaya would have/allow them, then I'll repeat what I posted in another thread. We have not yet made any determinations as to if or how third parties may list or offer tickets on ePlaya for the 2013 event. That is a decision that will be made by Burning Man, not through a poll on this or any other site.
If you mean whether users should organize their own raffles, that's up to the individuals/organizations. Speaking personally
, I wouldn't recommend it. Aside from legal and tax issues (which are important), in the wake of ticket scarcity I find it distasteful. Before the first sellout in 2011, it was one thing for a camp or project that had an extra ticket (through generous campmate or grant award) to offer one up at a fundraiser event to raise a couple bucks. Those who didn't care to participate in the draw could easily purchase a ticket through regular means. After that first sellout happened and tickets were no longer readily available at any time, ticket raffles changed somehow. They were no longer tickets that nobody needed (who didn't know someone that needed a ticket at some point). To me it was hoarding and profiteering. Using the internet to promote and sell even more tickets just seemed to underscore that point. Of the things camps and projects would do to raise money for their efforts, that's probably my least favorite method.
In the spirit of disclosure, I've participated in Burning Man ticket raffles in the past. In 2004-2007 I bought raffle tickets at fundraiser parties here and there for various art projects. I never won, but was okay with the outcome of all of them. In 2011-2012 I didn't participate in any raffles. Aside from what I stated above, my girlfriend and I already had tickets and didn't need them.
The other thread was locked because not only was it calling the legality into question, but it was accusing Burning Man of a crime. That's a conversation to have with either Burning Man's legal team or the appropriate authorities, not one to have on the message board. I will be pruning this thread to remove posts that attempt to do that here - please direct those questions to Burning Man (you can use the firstname.lastname@example.org
address and it will be routed to the responsible individual).
