Inviter badge

The Inviter Badge was a Roblox badge players received when they invited three or more users through email, or if three users entered their username in the referrer section of the Bonus Round page. Like the Friendship Badge, it is considered a social badge.
The Inviter Badge was retired on October 14, 2013, although the referrer section of the Bonus Round page wasn't removed for another two years. The badge continues to show on players' profiles after its retirement.
