No idea why they worded the article that way. The person going to prison is the person who leaked the documents and was also the admin of the discord server they leaked it to.
maybe it is modern propaganda, maybe the author is just incompetent moron trying to get as much clicks as possible 😔
Discord servers are restricted ring-fenced sections of the internet. They are often used by gaming groups and communities as secure chat rooms but are also used by fringe organisations to push their ideologies and discuss wild conspiracy theories and plots.
but likely just a useful idiot for the people in charge
that's little bit too harsh. the authors of the article write general news, they do not specialize in technology, and it is pretty clear none of them is gamer (i suspect that telegraph correspondent to united states doesn't have much free time to waste on gaming 😂).
so while that paragraph is stupid to the degree where it is bordering on funny, i am not looking for malicious intent behind it.
