YT blocks video automatically

Hey everyone!

I recently tried to use the wellknown method of downloading a video on YouTube, edit it a little and reupload it.
This is what I did- I downloaded an older music video (2008) of a famous artist, watermarked it and put one slide in the
end to make it longer. Then uploaded it.

What happened? YouTube blocked it automatically, from the first second. It directly shows it when I click on my Video Manager.
As a reason they say that the video content and the audio content was recognized to belong to EMI.

Does that mean the times of reuploading are over and it's not possible anymore to reupload videos due to that automatic software YT apparently has?

Thanks!

YT just updated their system.

Looks like the "edit" method wont work anymore.

But how is it possible, when you edit a file , ID/hash/fingerprint of that file changed ? how they find it is still the same video ? Someone reports manually , or ?
