If your company uses the Microsoft ecosystem, have a look at the search function in Delve or SharePoint or whatever the fuck they're calling the shared employee document repository this week.

At one point, I don't know if you still can, the search would scan meeting transcriptions if the organizer fucked up the privacy settings.

I searched for naughty bigboy words and came across a transcript of two employees (who had since left the company) just absolutely shittalking a manager.

Besides some hilarious typos I also found some old chat logs where I was using some colourful language. Deleted that. Hopefully it's proper gone and HR won't find it.
