Can giveaways that are completely free, with both no cost for entry and no third part verification be universally permitted? I say this as I would not like to have to ask an admin every time I do a give away for random reasons.
As long as there is no "buy in" or other cost for entry you are free to give away stuff as much as you want. The rule is mainly for raffles, etc. where people are required to make some sort of payment or "contribution" in exchange for a chance at a prize. They often end up being scams or just mismanaged, so we just completely disallow them.
