If you've ever worried that Netflix is keeping track of your viewing habits, this story won't put your mind to rest. In my defence, though, How I Met Your Mother is a really great show, and I'm only watching the entire series all over again because my teenager wants to watch it. Honest.
But this week the streaming service took its gathered information and used it to troll people on Twitter in what looks like a pretty clever marketing campaign for a Christmas film I've never heard of called A Christmas Prince.
"To the 53 people who've watched A Christmas Prince every day for the past 18 days: Who hurt you?" Netflix US asked.
Apparently A Christmas Prince is a cheesy romantic comedy about a journalist sent to report on a playboy prince. Presumably at Christmas. Of course, there is a case of mistaken identity, a monarchy in crisis, snow, horse riding, and some falling in love. And it's a Netflix original.

And of course the clever tweet caught people's attention and got a whole lot of conversation going.
Amanda Bell responded, "Why are you calling people out like that Netflix?"
Netflix said, "I just want to make sure you're okay."
Amanda answered, "You're not my mom."
"Ok sweetie," said Netflix.
Luckily Amanda has a sense of humour. She came back with, "I'm telling Dad," and proceeded to tag rival streaming service Hulu.
Netflix's statement, and the exchange with Amanda got others worried about how much they've exposed themselves with their own viewing habits.
Kara tweeted, "Netflix, how many times in a row have I watched Friends since you put it up?"
Netflix's answer was swift and clever, "Not enough."
Some on Twitter were legitimately concerned about their privacy being violated, and "big brother" watching them, but most clearly got the joke.
And one Twitter user really understood what was going on here. John Hartmann wrote, "This is viral advertising for this movie I've never heard of but will now hatewatch because the interwebs say it's crapctacular, right? #wellplayed"
In a statement, Netflix reassured members their privacy was very important and respected.
"This information represents overall viewing trends, not the personal viewing information of specific, identified individuals," said a representative.
So now, thanks to some clever work from the Netflix social media department, you've heard of a movie they want you to know about, and you may even watch it – although 18 days in a row might be a bit much.
