Discord is making public server messages indexable on google starting november.
if you run a server:
server settings → opt channels out. do it now, before november.
If you’re a user:
settings → privacy & safety → data and privacy → turn off message indexing.
The default is on. the opt-out is on you.
things worth thinking about before november: any public server you’ve ever posted in. anything you said assuming discord was “just discord.”
Moderators can opt their channels out. users can opt themselves out. Neither of those things will happen automatically.
