Update: That was fast. Only 4 hours later, my comment is not to be found again on Youtube (see #posh comment here). Who will find it? No, I did not delete it myself and there can not be a prove, other than here on the blockchain where nothing is without traces, even deletion and censorship (as happened a lot with the Steem/Hive fork).
Here is another take, reaching in to Russell Brand.
