Ok, from what I’ve found, these are all officially confirmed. Don’t trust any accounts that “claim” they are the boys unless they have proof.
One Direction: @onedirection
*note: they haven’t updated these accounts at all
Zayn’s is private.
Don’t bother messaging for One Direction’s urls.
Niall tweeted that he never had one.
Liam used to be ohnoitspayne. (It WAS real, he announced it on Facebook, only to delete the tumblr account a day after.)
Louis is therealtommo but his account is password-protected. It used to be open to everyone.
The Zayn and Harry accounts could be real, or fake accounts.
But even if they are, I think after all the work they’ve done, they should at least get their privacy online.
All i can say is that the only confirmed account is onedirection’s official tumblr.
So show some love & support by following them! ♡
