Deleting videos is actually a topic I wanted to address for quite some time now.
Are only the resource files gonna be removed or all versions of it at some point? I already noticed that a lot of my old videos are not available anymore, neither in the original nor in the 480p version. I constantly have to re-upload them for them to be available again.
Recently some of my videos didn't even survive more than a couple of days. It can't be, that videos are getting deleted within less than 7 days when they are still suppose to generate income.
For me that's a big problem of this platform right now. If i can't be sure that videos will be around for quite some time DTube can't be an alternative to YouTube right now.
