Apparently they don't even reupload it, they ask Youtube to get rid of the downvotes. The downvotes disappear all of a sudden , while the (few) likes remain. Is that even possible? You can pay Youtube for modifying your like/dislike ratio?
EDIT: I think that they don't delete it, because I didn't watch the video entirely and it was still on my "unfinished" list.
Money talks. Youtube is barely making a profit so they will gladly accept some extra income . Youtube rules were for that reason always a bit 'subjective'.
In the wilderness we go alone with our new knowledge and strength.
