hmmm. No you should be ok.
As I understand it, Youtube works this way.
Youtube got a bunch of mods. They decide - within the rules wether or not your movies are ok.
If somone flag your movie - a mod will have a look at it.
If you have less then 3 movies, and you break the rules, you account dies.
If you have between 3 and 20 movies and you break the rules, the movie die and you get a warning. If you do it again - your account dies.
If you have more then 20 movies you get 3 warnings before your account dies.
They are hardcore nazzies on porn or pornrelated and violence thease days. Guess it's becourse the youtube staff has more women then men.
here what I think has happend to you.
You uploaded the same movie again - what rule you broke, I don't know, but it can be one of your other movies that broke the rules. If it get's flaged for what ever reason, and the same mod sees this video again, she gets pissed and just nukes you. Your IP might be on some kind of observation wich is why I recoment you to use a proxy or just wait a few days.
