Don't think this is a joke of something, as it can happen to anyone who use similar method. I hope we all learn from this person's mistake to avoid becoming the next victim of such situation.
It seems like a joke to me, because who would have a picture of their keys together with a hardware wallet on them? So that person first took a picture, and then allegedly lost that same set of keys?
Even if we ignore the first aspect of the story, why would he ask for the keys publicly and offer such a large reward if he has a backup with which he can recover his coins on another hardware wallet? Of course, we can assume that this person does not have a backup (which is really stupid), or that he does not understand that the coins are not on the device itself, but on the blockchain.
In any case, if there is truth in this, then it only proves that people are the weakest link in the security chain - because if you provide them with a device for safe storage (which Ledger is not really) and give them the possibility of creating a safe backup, they do such stupid things...
When I think about it a little more, this looks like a bad advertisement for Ledger (given the geniuses from that company, I wouldn't be surprised).
