My deleted videos

So I got up yesterday and clicked on my profile and noticed there were no videos posted under my name. I had about 20 of them. Some being there for several years and 100,000-200,000 views. Why were they deleted? A couple I expected were listed as copywrite complaints but the ones that were years old were mostly amateur videos and were not listed as deleted for any certain reason. How irritating. It takes forever to load a video and have it posted. Why would I bother posting more if they are just going to delete it? They are making money off my work you think they would try a little harder in not deleting stuff for no reason. Sure there were not a lot of videos but that is not the point here.
