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.
They might be referring to lemmy.zip. Imagine this email.
Many things will render that as a clickable link. In case it didn’t, here is an explicit one. https://invoice.zip Go to this website. It explains the risks. In case it isn’t clear, zip is both a common file extension as well as a top level domain now. This means that it is great for phishing.
But I’m confused why OP thinks this is a problem on all specifically. Your client only talks to your instance. Only Lemmy instances talk to each other. Your instance does all aggregation for you.
One of the ones marked as sus, yes
