Yup. I was able to identify the employee running my company's subreddit that was hosting a current/former employee hatefest and many, many leaks, fueling RTO protests and unionization. Took all of about 30 mins of digging through his comments to figure it out. I never acted on it because I support everything about what it would lead to, but if I could figure it out, so could someone smarter than me who works for the interests of my company. He was still at the company, last I checked about six months ago.
