Maybe the bruteforce protection can be tweaked in a way that only different room attempts or passwords end up brute force throttling.

Research direction

Start by tracing the room API requests shown in the report, especially GET /ocs/v2.php/apps/spreed/api/v4/room/ABC and POST /participants/active, through the brute-force protection handling. Reproduce the repeated 404 requests after a room is deleted and determine whether throttling should distinguish deleted rooms or credentials. Done means the unwanted lockout is prevented and regression coverage verifies the intended throttling behavior.
