Throwing this up for posterity, since the account ages are pretty close together:
Tigerhallam joined the site on 13 Jan 2014, 13:59
AmirthePersian created their account on 15 Jan 2014, 12:43
I'm betting they're IRL friends, though Tiger's only activity on the site is one draft thread of his own and the rest is on a draft of Amir's. I asked them to post simultaneously, (which admittedly doesn't prove much, but they do seem to both be in the same timezone), and screenshots will follow since the thread will likely be deleted soon.
