A live broadcast that carried on for 11 days has raised ethical questions about streaming trends. An Australian creator named Norme succeeded in his attempt to stay awake for 264 hours in a row, though he was banned on three different platforms in the process.

Norme attempted to forgo sleep for 11 straight days in order to certify himself as a Guinness World Records holder. Though the actual record is nearly twice as long, that person used stimulants, and Norme planned to eschew uppers during his attempt.

There’s just one problem with that plan: The feat Norme attempted (and eventually pulled off) is extremely dangerous. People who completed similar challenges warned the streamer that it would take years to undo the damage he caused for himself, if he could even undo it at all.

“Sleep deprivation like this can cause serious damage to the brain,” said commentator Philip DeFranco in a video discussing Norme’s stunt.
