By safely, I mean that the video I steal from someone else and upload to my account doesn't get blocked/banned etc. I don't mind giving the original uploader credit. My mission is not to rank the videos so I don't care about rankings. I need to use them on my website as how-to/instructional videos. Or how about I steal the video from YouTube and upload it onto other sites such as Vimeo (recommend the best one?) and then put that on the website? Is this better to do?
