I recently read the itch.io content creator quality guidelines and it has an item that states "Do not create paid content to enter a contest, anything that resembles real money gambling, or content that resembles pyramid-schemes" and I thought to myself "is this considered resembling real money gambling...?", and so, I put the disclaimer there just in case. Granted, I checked the details of the page and it basically said not to sell people things that allow them to make literal money but "anything that resembles real money gambling" is kind of vague wording?
Honestly, I put a fair amount of detail into the tutorial but it seems that some people are still a bit confused about some of the less obvious mechanics, so I'm not quite sure what to make of it all.
