This happened to me years ago. Suddenly got a random community guidelines violation on YouTube for a 3 second VFX shot that was not pornographic or violent and that I owned all the rights to. After that my whole Google account was locked down. I never found out what triggered this response and I could never resolve the issue with them since I only ever got automated responses. Fuck Google.
If you wanna expand your site in the future, something like Kirby CMS might be great. It is paid but dev experience, community and loading speed of pages are much better that with something like Wordpress.
