Though in the past I hosted 5-6-7-8 I don’t know how many games... all in speculation

I've seen many free raffles in Collectibles too (
example). Moving those topics to Games and rounds feels like killing those very nice community giveaways, it doesn't justify the effort and money someone puts in without expecting anything in return.
In my opinion, Games and rounds is a great board for commercial games, such as promoting a casino, but not for community "games".
I don't moderate the Collectibles board that often so I'm not sure about the status of physical collectible giveaways / free raffles. I've messaged theymos about it and I'll post what he has to say (or edit it into this post) when I hear back from him (and if he gives me permission to do so).
