Go Private? (aussie.zone)

Lemmy 0.19.11 (which I've just upgraded AZ to) has a new feature to allow regular federation, but require users be logged in to view content.

I'd like to gauge feedback from users on this. It will not add privacy, or limit the propagation of posts/comments etc. But it will limit AZ server resource consumption by bots or users that are not logged in.

Thoughts/concerns on enabling this feature?

Update: thank you all for your thoughts and feedback on this. We'll leave AZ as it is, though may use this feature in future if we need to mitigate attacks or other malicious traffic.

It's a simple tick box in the admin settings interface. Trivially easy to enable, and presumably disable. Doesn't appear to even require a service restart.

Is it possible to automate? I looked at the Lamington docs briefly and it looked like it uses a file to store config. Thought if the config file was a symlink it would make it easy to change config to be private / be public.

Like this every 30 minutes or whatever. Obviously will require a bit more logic rather than constantly recreating symlinks... but yeah.

#!/bin/bash

THRESHOLD=1.5

CMD_HIGH="ln -sfn /blah/blah/config.json /blah/blah/config.json.private && systemctl restart lamington"
CMD_LOW="ln -sfn /blah/blah/config.json /blah/blah/config.json.public && systemctl restart lamington"

LOAD_15MIN=$(uptime | awk -F'[a-z]:' '{print $2}' | awk -F', ' '{print $3}' | tr -d ' ')

if (( $(echo "$LOAD_15MIN > $THRESHOLD" | bc -l) )); then
    echo "[$(date)] High Load Detected - Current: $LOAD_15MIN, Threshold: $THRESHOLD"
    echo "[$(date)] Taking Lamington private........ "
    eval "$CMD_HIGH"
else
    echo "[$(date)] Normal Load Detected - Current: $LOAD_15MIN, Threshold: $THRESHOLD"
    echo "[$(date)] Returning Lamington to public... "
    eval "$CMD_LOW"
