The ‘it’s clearly fake’ narrative is an odd one to me.
Agree if it was, the papers wouldn’t have published it to start with.
secondly, if someone was going to fake an image of Harry, surely they would have him doing something more interesting or scandalous than this non event.
the only reason this is a story is because of the rank hypocrisy in Harry “I fear for my life in the UK” wandering about in public knocking on strange doors. He’s obviously not afraid for his safety and it clearly shows he’s perfectly safe - so his demands for tax payer funded security are just about status and wanting to save himself the cost.
Aside from that it’s just really weird behaviour. If a friend was expecting him, surely you’d just ask them to drop a pin or you’d get your security to find the right address before approaching the door. And if they weren’t expecting him, why would you just rock up at the door on the off chance? Surely you’d text or call and ask if they were free for you to pop round.
