There isn't any steganography (at least for the flag that I found). They have a bot that actually "reads" your post, which you can verify for yourself. This is alluded to in the message that you get when submitting a post:

> Your post was submitted for review. Administator will take a look shortly.

How can you verify? That's what I was stuck, it's hard to test things if you're not getting any sort of feedback. That message seemed pretty constant.

EDIT: I see, managed to verify it by putting an image on my own webserver and seeing the log hit. I got a rough idea now, thanks!

EDIT2: Got it :)
