Does Niall Horan have two instagram accounts? Does Harry Styles have more than one?

[Rachel]

I know that Niall's instagram account is @nialler1993 and I believe Harry S's is @harrystyles. The thing is that, on instagram 2 accounts, @niallerhoran_93priv and @harrystyles02 have been having a fight. They claim that they are Niall Horan and Harry Styles but is that true? People say they're fake accounts, but the Niall account posted a pic of a Niall Horan signature on notebook paper. He said " for those of you who don't believe." That attitude doesn't seem like Niall. anyways, I looked and it's not on images, so does that mean Niall actually has that account and he drew that? Does this mean that Harry and Niall are in a huge fight because if Taylor Swift? Is that other account Harry's also? Please try to answer all the questions I have asked if you can. Thanks!
