Hey, I advocate https even for LAN only, most people don't think about the Wifi attack vector. That's why I use self signed certs on my LAN stuff, I just don't care about that yellow padlock that disappears when I trust the website. I've only experienced a single app ever that didn't accept self-signed (I'm looking at you wallabag app).
I can understand how it would be different if family members suddenly starts asking if it's true when their devices tell them the webside is potentially dangerous.
Yes, it's dangerous to surveillance capitalism
People... watching money?
Forget it, I'll set it up with a regular cert and external access
on your instance you shud ban but
haha evil wins again!
Jokes aside, most offensive posts mostly originates from different instances with vastly different user culture. Downvoting posts works in the way that it lowers the visibility on your server but the offending poster might be on an instance that disregards downvotes so they "won't get the message".
It's much more effective to just block the poster, or the whole community if one so desires.
