-`notify_exclude` is an optional list of masks [OperServ NOTIFY](Services#operserv-network-operator-tools) never announces, so they cannot flood the feed. It uses the same grammar as a watch mask: a `#channel` mask mutes that channel, and any other mask (nick glob, `user@host`, extban) mutes a user. The classic user case is PyLink relay clients — their nicks carry a `/network` suffix — so `"*/*"` silences every relayed user; a channel entry like `"#staff"` keeps a broad `#*` watch out of that channel.

+`notify_exclude` is an optional list of masks [OperServ NOTIFY](Services#operserv-network-operator-tools) never announces, so they cannot flood the feed. It takes three kinds of entry:
+
+- `#channel` — mute that channel (keep a broad `#*` watch out of `#staff`).
+- `server:<glob>` (alias `via:`) — mute everyone on a matching server. This is the handle on a relay whose users have **clean nicks**; the server name is what prints after `via` in a feed line.
+- anything else — mute a user: a nick glob, `user@host`, or extban. `"*/*"` catches PyLink relays that suffix nicks with `/network`.

+Excluded masks are skipped by *every* watch, so genuine locals still surface while the relay noise is gone. An entry mutes a **user** (nick glob, `user@host`, extban), a **channel** (`#staff`), or a whole **server** (`server:<glob>`, alias `via:`). The server form is the one that catches a relay whose users have clean nicks — `via chatnova.relay` in the feed becomes `server:chatnova.relay` in the list:
