Some of the sports related X giveaways run by Budweiser are good. Also prolific on X are many gamer giveaways. Not interested myself but others are. Most of them seem pretty iffy to me and are open worldwide which I usually avoid. Now on Instagram, there are plenty of giveaways that are not cosmetics but yeah, they are very common. Don't enter them just to be entered into something because that teaches IG's algorithm that you are interested in them and more will show up in your feed.
