Is the guild lottery addon ok to use?

Q u o t e:
I wanted to see if our guild can use the addon from curse.com, guild lottery. I hear from some people that its illegal and other people say its okay to use. How do i find out?

I'm unable to specifically state whether a particular addon is definitely against our policies. Can you describe exactly what this addon does though? Perhaps I can help identify addon behavior which might go against the spirit of World of Warcraft.

Q u o t e:
its only in your guild, and from what i see when you buy a ticket it goes into a pot and then the winner get the pot. We are a small guild and thought it would be a fun thing to do once a month if we are allowed

Provided that you do not advertise it within in-game channels, and no scamming or exploitative activity takes place, a guild lottery should be okay. Please note that 'potentially okay' does not mean, 'supported'. We will very likely not be in a position to provide support regarding any losses that might be incurred during such a guild event.

I'm unable to endorse any particular Addon. In answer to your question though, If this addon operates exclusively out of the Addons folder, has no components elsewhere and otherwise does not violate our policies, then it sounds like it abides by our Addons guidelines.

As always, please remain cautious when downloading addons, and run scans to ensure they do not contain any malicious programs.
