Twitter boss Jack Dorsey briefly got booted from his own social network — and the chief executive insists he wasn’t hacked.

“Just setting up my twttr … again,” Dorsey tweeted late Tuesday evening as he restored his account — about 90 minutes after his account was briefly marked as “suspended.”

Dorsey — who was making a sly reference to his initial “just setting up my twttr” tweet when the social network launched in March 2006 — added the suspension was an “internal mistake.”

That looked like a bid to quash speculation that Dorsey’s account had been hacked in the wake of a Twitter crackdown last week on accounts of prominent “alt-right” activists.

The Twitter housecleaning follows criticism that it hasn’t done enough to respond to abuse and cyberbullying on its platform.

Among last week’s casualties were Richard Spencer of the National Policy Institute, who a few days later led a conference in Washington at which his supporters gave a Nazi salute.

Twitter officials didn’t respond to requests for comment Wednesday.

Left unexplained was a precipitous decline in Dorsey’s Twitter followers in the wake of the incident to as few as 124 from 3.8 million. As of Wednesday evening, the number had recovered to just 39,800.
