Introduce a rapidSpamTracker to detect same messages posted across channels within a short window and return prior message IDs for cleanup. Refactor spam detection to collect scannable text from message content, embeds and attachments, simplify role-ping and link heuristics, and mark spam when a role ping + link is duplicated across channels. Update index to use the tracker/collector, delete prior spam messages, improve moderation flow (ban → kick fallback), report clearer action/error labels, and warn about missing channel permissions. Update commands display text for detection/actions and bump .env.example MIN_ACCOUNT_AGE_DAYS default to 7.
