The only way these influencers and their relatives secure their safety is to maintain a lowkey status. When you are in an industry where you become popular to the public, you already expose yourself from people with bad motives. It's the price you pay for your popularity and to protect your loved ones, you don't reveal to the public that you are related to them. They should also avoid going to crowded public places or use a disguise when going out.

As a person, influencer or not, you should never reveal your financial status in the public.
