What does "the eternal September" mean?

We still have voting, mods, and admins. Mods can take action for bad content, admins can take action for chronic offenders, or if mods aren't taking care of a community. And worst case scenario, if an instance is causing trouble as a whole, it can be defederated.

Down the line, I think we'll see spam lists to help deal with people creating lots of spam instances, like email has.

I'm wondering the same, I would guess grey listing and shadow banning to be the most effective.

you don't know do you
