Well, maybe not literally, but it had to be Ianto's fault metaphorically somehow. Or, admittedly, he should have had up-to-date safeguards against guerilla advertising of this and all other calibers, and he will, at some point, when he's not busy. "Personal hell? Sounds festive. You shouldn't have touched it, they probably have your bank account now." Though joke's on them, Ianto's bank accounts, if any, are probably in an entirely different universe. And also maybe not tied to his bioprints, at this point in time. Still, it never hurts to be careful. There are a lot of scams out there designed to take advantage of the old and infirm. You know, the type of people who touch advertisements without thinking. If they get a call tomorrow saying that 'one of the household computers' is infected, he'll know who to blame.

Scam or not, the Doctor is already a little invested, looking for the source of the communication, verifying its existence as something besides a trap. Though, it would be a pretty poorly designed trap, at least if it's geared towards him. Even a tagline about its potential dangers doesn't make it much of a draw. Mostly what's curious about it is how it was targeted, though nothing says it even was. Though it is impressive how little they actually managed to get right, and the Doctor feels the need to correct them on a few of the finer points of the holiday. So maybe it would be a better trap than he'd initially calculated. "Looks like it's real enough. Maybe we should check it out. Make sure the elves are up to code." He could be joking. He probably isn't.
