Looks like someone swept the address. Too bad they didn't post to here or reddit!
Well, finders keepers.
The imgur link is a Caeser shifted (hence Clooney in the film Hail Caesar!), which points to this QR code:
The QR code scans to
This is impossible to break if the cipher key is randomly generated and kept a secret, but I provided you the key:
You can quickly grab the ascii values of all these characters by looking here: http://asciivalue.com/index.php
Then all you have to do is subtract the ascii values from each other.
I'll do the first three characters here in detail:
The full process:
And that's how you do it!
I wrote a tool in c++ that does OTP encryption, and it will spit out a ciphertext, decrypt, generate pads, take custom pads, etc: It took a lot less time to set up the challenge than to write this post.

Some QR readers don't like displaying some of those characters because they aren't regular numbers, letters, or symbols. This is the encrypted private key--it is encrypted with One Time Pad (OTP) encryption. Hence the "pad" references. This is impossible to break if the cipher key is randomly generated and kept a secret, but I provided you the key:
Code:
Check out my pad, bro! I didn't buy it, I wrote it!

I wouldn't have a chance in hell even if I got the picture but nice to know the answer
