Option to tag projects as SFW, NSFW, 16+, 18+ etc

Tagging projects as NSFW would be incredibly helpful. Many NSFW projects I see have A LOT of children auditioning for them because they do not state that they require 18+ talent only. Also helpful for NSFW talent to actively search for those kinds of projects.
Also some verification to make sure that the person auditioning is of appropriate age. AND the person creating it as I've seen children/minors create NSFW projects as well.
More nuance age-rating tags like 16+ also would be helpful.
