A user on tildes describes how to go scorched earth for mods:

Turn off all spam filtering

Disable minimum karma requirements

Allow all posts, disable all rules

Unban all banned users

Purge all allowed submitters

Turn off AutoModerator, Scrub all configs

Delete all CSS and uploaded images/maps

Blank all sidebars, Delete all flairs

Allow NSFW content, Enable sub's content on /all

Set the sub's color scheme on mobile to something vomit-inducing

Blank all of the text options such as the sub's topic listing

Grab a copy of anything in the wikis worth saving

Disable and permanently remove all third party mod tools and bots

Invite all users to the moderation team with full comment/submission privs

GDPR request for their own account data and then

Use it to delete their accounts and all of their content

The options in bold, they have no defense for. That's where the pressure points lie. The rest they can cope with, but not those options, not if lots of subs and users go that route.
