Random videos posting on my account

I already sent in a report and did all of the security steps (changed password, added two-factor auth, managed devixes, and got rid of third party permissions like CapCut) but was wondering if this was happening to anyone else:

Random AI videos are being posted to my account narrating stories from Good Novel or Moto Novel, even after I completed the security steps.

I tried to see if any other related posts are being posted to other people’s accounts but so far, it just seems like these posts are posted to bot accounts. Idk why this is happening to mine
