That's what YouTube star Tyler Oakley found out when he explained why he doesn't follow Liam Payne on Twitter (but Liam follows him). A fan asked why not, and he responded: "It's important to keep my timeline flawfree."
Oh no he didn't. (He did.)
As you can imagine, a s**tstorm of angry comments were aimed at Tyler, as loyal Liam supporters came forward to fight the good fight, with the hashtag #liamdefensesquad.
As these things go, some of the comments got pretty mean and hatery. We're all One Direction af, but death threats and hateful comments are a little too extreme.
Tyler's comment about keeping things "flawfree" is likely referring to Liam's support last year of Duck Dynasty despite one of the show's stars making a homophobic comment. At the time, Tyler had tweeted: "Wow. Very confused and disappointed by this @Real_Liam_Payne tweet. This literally changes everything..."
He added, "If you defend someone actively supporting bigotry, homophobia, and ignorance, we're not on the same wavelength to even have a discussion."
Liam has steered clear of any drama over Tyler not following him - we suppose with fans coming to his defense, he doesn't have to say anything, right?
Sooo, are you Team Tyler or Team Liam?
