ASIS-CTF Finals 2014 - Fact Or Real? (75pts) writeup

The description of the challenge was: ASIS_md5(motto)

It really doesn't say a lot about what we need to do. First thing I did was checking on the ASIS team to see if a member has a similar handle:

ASIS Team https://ctftime.org/team/4140

Team members:
factoreal
lisbeth

ASIS Team has a member named factoreal, let's find out about him. Maybe he has a twitter account:

Sure he does, now there isn't much about this in his tweets, maybe the gallery would reveal something interesting. There are a couple screenshots about the scoreboard of the CTF, but this last picture is much more interesting:

The caption says: fact or real
