Since she joined Tumblr last summer, Taylor Swift has been permanently present on the site, using it to update her fans on news and engage with them to offer everything from advice and protection to gifts.
However, since the Brit Awards last Wednesday, the Swiftie fandom has been divided, and Tumblr has gone into meltdown, with fans angrily messaging each other and Taylor and the singer suggesting she's close to leaving the site altogether.
It all started when Taylor posed for a photo with a fan called Johnnie during the Brit Awards red carpet last week.
Some Swifties claimed Johnnie had "bullied" them in the past and were therefore angry that Taylor sent him Valentine's Day gifts and stopped to talk to him at the Brits.
One of these Swifties, Jessica, shared screengrabs of comments Johnnie allegedly made to her.
The fan claimed Johnnie left these comments on Instagram, calling her account "ugly".
As well as "dumb and annoying".
And calling her an "attention seeker".
She also shared further screengrabs of text messages and other comments from Tumblr allegedly posted by Johnnie.
Jessica went on to reply to another fan, telling her Johnnie had "made fun of her eating and body issues".
Things then escalated to the stage where the bizarre hashtag #SwiftiesWantTaylorSwiftDead began trending on Twitter.
The overwhelming majority of tweets including the hashtag were ones of shock and disgust that it'd been started in the first place.
