YSK: Browsing "ALL" at work might get you pulled into an office, even with NSFW off.
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.
Gah!!! Ffffuuck me I forgot about that. I take business calls on my phone through work WiFi and maybe I use my personal phone on breaks and such.. woopsie. So how bad does it look if I used an app or even a game without turning off wifi?
Overwhelming majority of workplaces won't give a shit. There's so many real issues to deal with and what games you have running on your phone is not one of them, that's a management problem - not an IT one.
Some incredibly high security environments might think otherwise but they'd never let you use your phone for business, you'd certainly be given one from the company.
