If you found content that shouldn't be in edpuzzle, there are a few things that we need to check first before taking it down.
1) "I found this video on the YouTube/Vimeo channel". When you search on YouTube or Vimeo, you are searching in the trillions of videos in those websites. We filter some videos, but we do not have control over the content coming from these sites. Fortunately, the video library of edpuzzle is only available for teachers and the students will only see the videos that you assign to them. This means that you as a teacher will be the filter for your students' content.
I hope this was helpful. If there is anything else that I can help with or clarify, please let us know. I will be more than happy to work past office-hours to answer your questions!
