Why YSK: It appears several Lemmy Instances are flagged as suspicious and at least 1 instance intentionally using the name of ransomware. A couple of the big enterprise monitoring suites (Fortiguard, ZScaler) will flag your account and may end up with you being pulled into an office for an explanation, or worse.
TL;DR: Keep browsing to your local instance at work for now.
If you are on their network they can see what you are doing. At the end of the day, the business will protect itself.
Do what you want at your own risk. But never assume that any company is on your side.
