If that is him, it looks like we have a genius criminal mastermind on our hands... he was in the news for calling the cops on himself:

Update #1: that news article was posted as early as August 2011 and mentioned him going to jail for 10 months, but he registered an account here and began posting in February 2012.

Update #2: very strange how that FB profile is full of nothing but cannabis-related photos, but none of his posts here even mention it (there is some talk of Diablo 3 in the early posts), and that profile has not "liked" anything Bitcoin related... not too sure it's him.

Update #3: Just found a 2nd FB profile of "David John Williamson" (https://www.facebook.com/davidjohn.williamson.3) looks to also be his account based on the pictures. 2 more photos of him there, nothing found on Google Image reverse search and no GPS coordinates given in embedded EXIF data.

Can someone do a "catfish" and message some of his more active Facebook friends, get them on the phone to verify this is the guy we want?
