Uh huh. I'll be sure to hold that party where I registered the keg at. Riiight...
I see people peel labels from longnecks all the time. Do you think this "sticker" will be (pun intended) "sticking around" on the keg, especially if it points to the perp?
I'm REALLY surprised they didn't think of putting serial numbers on the kegs and track them back to the store, thus making the store liable regardless of who bought the keg.
