Got 8,000 pre-registrations via a YouTube comment, but my 380k TikTok account got banned. I will not promote

Hi everyone, I’m building a vertical short-drama app using Flutter and Supabase. To test the waters before launch, I pinned a simple text comment under a few videos on my gaming YouTube Shorts channel. People actually searched for the app on Google Play, and I reached 8,000+ pre-registrations. However, right after this, my TikTok account (380k followers) was permanently banned. It seems this cross-platform promotion triggered an algorithm penalty. Now I’ve lost my main marketing channel right before launch.
