"I'm pretty sure when you post the link kinktalk visits it for metadata and immediately invalidates the link. Not a single post in this thread has been successfully visited by anybody."
So it looks you're right, thanks for picking that up, the problem is the link gets validated by our system destroying the one view.
To get around this you will need to modify the link when you copy it into your message. Use something like this,
https:// (remove space) file.io/ZE5BMi
And yes this is a valid link...
