On Thursday, Mac Miller was sharing new music on Instagram and tweeting about how excited he was to go on tour. On Friday, he was dead, from an apparent overdose. It's no secret that Mac struggled with substance abuse. He rapped about it, and often turned his personal wreckage into great music. But it seemed like he turned a corner. On his new album, Swimming, he sounded like  his head was above water. Then he drowned.

Fans mourned the 26-year-old rapper, sharing what Mac meant to them and encouraging others battling addiction to seek help. However, shortly after the news broke, trolls began blaming Mac's ex-girlfriend, singer Ariana Grande. The couple dated for two years, and broke up last May. After the split, Mac spiraled out of control, drunk driving, and smashing his G-Wagon into a pole. He fled the scene, but the police tracked him down, arresting him for a DUI and hit-and-run.

At the time, a Twitter user blamed Ariana for Mac falling off the wagon. The singer defended herself in an impassioned post: "I am not a babysitter or a mother and no woman should feel that they need to be. I have cared for him and tried to support his sobriety & prayed for his balance for years... I will continue to pray from the bottom of my heart that he figures it all out and that any other woman in this position does as well." She added, via tweet, "pls take care of yourself."

Now history is repeating itself. Trolls have flooded Ariana Grande's Instagram with offensive comments, blaming her for Mac's death. "THIS IS YOUR FAULT!" wrote natalie_dope, and many other users. "It's crazy because you really did kill him," wrote zay_mk6. "I HOPE YOU'RE HAPPY WITH PETE," wrote thourtje.  (Ariana is currently engaged to SNL star Pete Davidson. In one of his final interviews, Mac said he was "happy for her.")

Reportedly the situation got so bad, Ariana Grande had to deactivate her Instagram comments. The comments have since been reactivated, and fans are rightly coming to the singer's defense. "She has nothing to do w/ Mac Miller’s choices," wrote @RealKhalilU.

"The amount of tweets blaming Ariana Grande for what happened to Mac Miller is disgusting, his addiction and lack of help is what drove this to happen, don't point the finger and blame," wrote @J4CKMULL. "All she did was to remove herself from a toxic situation. She wanted him sober. There is nothing wrong with that," added @inihelene.

Ariana Grande has not publicly responded to Mac Miller's death, as of this writing. But it's safe to say that she is just as devastated as Mac's fans. Blaming her for his apparent overdose isn't fair, and adds insult to injury.
