Bloc is strictly for 18+ year olds, so in an ideal world you wouldn’t be able to advertise to anyone younger than 18. However, it is possible that younger people are posing as over 18 year olds and aren’t found by our age restriction technologies, which is why we also have advertising restrictions for those under 18.
Targeting and campaign options are not available when you create ad campaigns including audiences under the age of 18 in all locations. This is part of our overall efforts to strengthen the privacy and safety of younger users across our platforms.
