Someone on Youtube by the name of HentaiSmut has been stealing NSFW audio from Newgrounds' creators, such as MissMoonified, MizzPeachy, and myself along many others. They also have a Patreon where they are trying to make money off of their stolen content. I want to reiterate that NSFW audio content is not allowed on YouTube as it is considered sexual content. Trust me, if I was absolutely sure it was allowed, I would have put them there myself on my account, but it is not. Putting in a DMCA claim unfortunately isn't the safest option for us as it requires putting in our personal information and thus opening ourselves up to being doxxed.
This has really made me reconsider whether or not I want to continue making free NSFW audio and posting it if someone is just going to steal it and make money off of it. Please flag, comment, and report the following accounts on YouTube. Content thieves should not be tolerated in anyway!

Dang wish I knew about the law I'd help you out.
