Videos being restricted

Hello, I have a growing TikTok account with 8K followers at the moment. My most viewed video had around 1 million views. Everything was going really well but recently, I’ve been getting restrictions on everything I post. TikTok restricts my video for people 18+ even though there is absolutely nothing graphic, suggestive, violent etc. I double check my videos. And I actually won 4 appeals already where they made my videos suitable for all audiences again. I have the feeling that someone is deliberately reporting my videos. Is there anything I can do to stop this? My views dropped significantly because of this.
