I'm almost certain it's not. In the UK I'd assume there's GDPR requirements that mean they need to keep track of it. I also contacted them a couple of years ago after we had a bullying issue and no history of it; Slack confirmed that they had the history and that they could give it to us, but as it would be PMs, they'd have to inform every member of the workspace when they did.
