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.
That won’t hide the IP and really doesn’t hide the domain name either if your company actually has any decent monitoring on the network.
General rule: if you’re on the company hardware or network just assume your IT department knows where you’re browsing.
