It sounds like OP has the same:
I scanned the initially concealed QR code on my phone, entered the also concealed code and was presented with a web page with info pertaining to a btc balance of 0.6104...ish.
Very interesting! I just went back to re-read the few replies after easternklaas made that post; it seems like all of us missed the implications of the "concealed code" he referenced. In light of what dkbit98 found on reddit, it seems like the OP's wallet is just a ruse.
Now that it seems this is nothing more than a joke, I hope easternklaas comes back and helps us get to the bottom of this weird event. At the very least, sharing the public key no longer seems like a privacy risk.
