Not particularly.

Here is my current point of view (I may be extremely wrong):

In reddit say someone posts spam and/or racism, sexism etc. Usually subreddit automods would catch and ban offenders. Only in extreme cases does reddit admins automatically or manually block unwanted content (with usually the worst case being a poorly moderated sub leads to the sub reddit being shut down).

In this Lemmy node by contrast would the admin of the Lemmy node be responsible for setting up a global auto mod to attempt to curb spam, hate speach with smaller group mods (ie subreddit mods not sure proper term) supplementing?

Just curious how moderation dynamics would work on Lemmy in general

Sry if I am being a bit broad
