Does anyone have experience running account that primarily makes videos set as 18+?

I'm wondering if "audience control: video limited to those aged 18 and over" will hurt my reach. I'm an artist that may draw horror or stuff that I intend for more mature people and I'd prefer if kids didn't interact with my profile, or at least limit it for them. Any insights?

If it will limit my reach then I might result to just putting a warning on description cuz otherwise there is no use using tiktok if I will get no people
