Adult Content: We do allow adult content on Blogger, including images or videos that contain nudity or sexual activity. But, please mark your blog as 'adult' in your Blogger settings. Otherwise, we may put it behind a 'mature content' interstitial.
There are some exceptions to our adult content policy:
Do not use Blogger as a way to make money on adult content. For example, don't create blogs that contain ads or links to commercial porn sites.
No incest or bestiality content: We do not allow image, video or text content that depicts or encourages incest or bestiality
