With Roblox recently giving users free avatar items for completing age verification, I think that this could be extended by encouraging developers to reward players if they have completed age verification. When Roblox initially added Premium, they encouraged developers to add “Premium Benefits” in exchange for premium payouts (now known as creator rewards).
Many games tend to reward players for favouriting the game, joining their group and encouraging players to age verify could also be added as an alternative to reward users. While I am unsure as to how developers could be compensated for this, I do believe it could improve Roblox’s safety features.
Developers are potentially missing out on additional earnings from 18+ American users due to them not being age verified and adding this can help with that.
Players could be prompted to verify their age in a game and the game that did that could reward the developer with small amounts of Robux similar to Tix for the referral. Amounts should be small to prevent misuse.
