“‘Someone’ cancelled my family’s flight out of the country at the last second,” Bray posted on Bluesky social media. “We got our boarding passes. We checked our bags. Went through security. Then at our gate our reservation ‘disappeared.’”

If there was a government stop on his travel, such as being added to a no-fly list, he wouldn't be able to simply rebook his tickets as the article describes.

Since the article does not explicitly say how it happened, you have to read between the lines. None of what they described sounded like government persecution, but it sounds exactly like what happens when you're targeted by 4chan for harassment.

Again, he was immediately rebooked by the airlines, and not taken away by DHS or TSA.

The article also makes it sound like the airline is in a bit of CYA mode, because at minimum they were the targets of a extremely high profile case of social engineering.

IMO it was really poor decision to make a public announcement about his intents to leave the country, prior to his actually leaving the country, especially since he's traveling with his family.
