* --ban-url: URLs which 404 and also match --sus-urls (bot-scan) * --ban-403: trying to access volumes that dont exist or require auth * --ban-422: invalid POST messages, fuzzing and such * --nonsus-urls: regex of 404s which shouldn't trigger --ban-404 in may situations it makes sense to handle this logic inside copyparty, since stuff like cloudflare and running copyparty on another physical box than the nginx frontend is on becomes fairly clunky
