I'm based in the UK but a large portion of my viewer base is from the U.S.
I was considering doing a "raffle" type contest where viewers would donate $1 to be entered into the contest, and then the winner would be randomly selected and given a prize like a Razer Blackwidow.
However, I've just realised that that could be perceived as gambling. Would it be better to phrase it as a "donor only contest" and say that only those who have donated can be considered for the prize? (We're doing giveaways for everyone in the channel, but as this was a more expensive one we wanted it to be limited to donors). I'm not sure what the laws are in the US about this or even which laws we have to consider, or what Twitch's policy is about this. I know some big streamers do subscriber only contests which would be similar to donor only.
