Rate limiting a plugin endpoint

Returning true from a by-value hook replaces the argument; by-reference hooks mutate in place — check the call site.

Hooks are the heart of MyBB plugins —

Code: PHP

$plugins->add_hook('pre_output_page', 'my_func');

is where everything starts.

The gid=0 trick keeps plugin settings out of the ACP — neat.

That hooks explanation finally made it click for me.

That has been my experience as well.
