Both are unofficial sites that mostly host unlicensed copies; MangaDex (official
API) stays on. Settings → Admin → Scraper → Hoster settings has a 'Use <source>'
switch. A switched-off source refuses new jobs, keeps queued jobs waiting and is
skipped by nightly update checks. Installations whose queue or history already
used a source keep it switched on, so upgrades don't stop a working queue.
