Fans of Tame Impala and Bon Iver received a series of nasty surprises courtesy of the acts' Twitter feeds over the weekend, thanks to the efforts of some hackers.

Pitchfork reports that the offending messages — which have since been deleted — went out June 5, during a period of several hours in which the artists lost control over their accounts and could only watch while they were used to spread violent and insensitive remarks.

Although the tweets have been taken down, some have been preserved through screencaps in Pitchfork's report. Tame Impala's account was, at one point, used to disseminate bomb threats toward JetBlue Airlines. Bon Iver's account, meanwhile, broadcast a series of tweets that included a callous dismissal of deceased boxing legend Muhammad Ali.

As previously reported, Sunday's social media shenanigans also included tweets targeting Tenacious D frontman Jack Black, who was the subject of a death hoax that had followers believing he'd passed away of unspecified causes at the age of 46. Keith Richards was also temporarily victimized, forcing the Rolling Stones star to explain that "hateful tweets" had been wrongly attributed to his name once he regained control of his account.

Like the Tame Impala and Bon Iver hacks, Tenacious D's loss of control over their account was relatively short-lived, and fans were soon apprised that Black was still alive and well. Tame Impala haven't offered any comment on their brief ordeal via Twitter, but Bon Iver offered followers an apology and an assurance that they'd taken back the social media reins.

Tame Impala's most recent studio release, Currents, reached the Top 5 in the U.S. after its arrival last July. Following a period of inactivity, Bon Iver returned to the road earlier this year, playing their first-ever tour dates in Asia.
