AFKAdvertiser
AFKAdvertiser sends a random chat message at timed intervals, which suits a player who stays idle on a server or in a world for long stretches.
What it does
The mod sends a random message after each interval. The first line waits a set number of seconds, and each following line waits that interval plus a random offset, so messages do not arrive on a fixed beat. The pool of messages is chosen randomly, and the count can reach 2,147,483,647 lines. An in-game toggle switches the messages on or off without leaving the game.
Internally a task runs after the interval and adds a random amount of seconds, aligned to the next full second, before sending the chosen message. Because the timing is measured from the previous send, the spacing stays irregular over long sessions. Only the client needs the mod, and the code is open source under the MIT License. It targets Fabric for 1.20.4 and has a public source repository and issue tracker for bug reports and feature requests.
Key features
Timed random messages
Lines are posted after a base interval with a random offset added, so the timing varies from one message to the next.
Large message pool
The message list can hold up to 2,147,483,647 entries, and each send picks one at random from the list.
In-game toggle
A keybinding turns the advertising on or off while the game is running, without editing a config file.
Sub-second alignment
The extra random delay is aligned to a full second after each interval, keeping the send times predictable in shape.

Use cases
Idle presence on a server
A player who sits afloat or waits for others can let the mod post a line now and then, rather than typing one by hand.
Recurring server notices
A player can list a set of reminders and let them rotate through chat at irregular intervals during a long session.
Who it’s for: Players who want chat lines posted automatically while they are away from the keyboard. The mod suits single-player worlds and multiplayer servers, since only the client has to run it.
How it compares
Join Message is server-side only, under a Creative Commons Attribution 4.0 license, and is not open source; its files cover 1.20.1 – 1.20.6. IntervalCommands is also client-side only and open source under the MIT License, but its files cover 1.21 – 26.2, so it does not target 1.20.4. AutoMessage is a client-side mod under the CC0 1.0 Universal license, with files for 1.20.1 – 1.21.8, and it is not open source.
