I don't think any of these videos were posted. Just videos that were the same. Including ones of nervous horses who were scared of jumping being forced into it and then not looking very happy afterward. I think one of the original video did involve horses jumping from quite high up into water over their heads, because I seem to remember people making comments about how it's ok because there was a Disney movie about it (Wild Hearts Can't be Broken or whatever it's called).
