Yes, YouTube has a very strict policy against channels that contain pornographic content or violate other rules. Creating a new channel on the same account after the old one has been deleted may be considered a violation.
Even if you create a new channel on a different account and do not post violating content, YouTube may still scrutinize your account and remove the new channel if they detect any connection to the previously deleted channel. This is because YouTube uses technologies and algorithms to prevent deleted accounts from reappearing with violative content. They may track IP addresses, account information, or other indicators.
If you have created a new channel with clean content and are not violating any YouTube regulations, you can try contacting YouTube support to clarify the situation and possibly reinstate your channel.
However, if you're facing this issue, it might be best to create a new channel on a completely different account to avoid deletion and maintain compliance with YouTube's policies.
