This is part of a series which I'll be continuing if this goes down well enough. If you have any feedback on the puzzle (too hard, too easy, not clear enough, etc) I'd appreciate it so that future puzzles can be better :-)
You wake up and log on to your computer. You log on to Puzzling.SE, browse some puzzles. You spend half an hour trying to think of number sequences because you're really desperate to go to a party, then after coming up with nothing, you get grumpy and decide to have a bit of fun - trolling people on StackOverflow with questions about the best way to become a lion tamer, for a career programmer.
Ha ha ha ha ha...
Pathetic newbie programmers, WHERE IS YOUR GOD-OBJECT NOW?
MUA HA HA HA HA!
-The SErial Killer
Terrified, you just sit there staring at the screen, until suddenly it redirects to a terrible, terrible thing and you snap into action, closing the window. You're not sure what exactly is going on, but in a rare moment of genius you realise that "SE" could refer to "Stack Exchange", and decide to see if any other sites on the SE network have been brutally murdered.
As you pull up the network sites page you see that yes, there are some other victims in this heinous crime. With no clues to go on, and nothing but a refined puzzling nose from weeks wast...err, spent on Puzzling.SE, you steel yourself and vow to bring the person or persons responsible for this to justice.
The only question is ... where do you start looking?
A hint for you, to narrow the search:
I didn't spend all that time making a fancy image for nothing you know! Graphics are hard (you can tell because of how cheesy it is :-P)
