Minecraft send texts automatically?

And I'm looking for a client or best LabyMod 3, which can automatically send a text to a chat. The client should work on a server like Griefergames. For me, automatic means: I don't have to sit on the PC and press a key, such as with LabyMod with autotext.

It depends, every hack client can do that, but only a little spamming. Otherwise it takes 20min to program something.

What do you mean any hack client can come from a message? Haven't I found it yet?

And how can you program something like that?

Depends on the purpose of what you want to do with it.

Well, I want to spam a message into the chat every 10 seconds
