Autochat dissapears after a while?

I'm running some NMZ hosts, and whenever I come to NMZ on my pure, I don't see their message popping up all the time, however, I see other messages from other people hosts. (except my bots).
Also, on the NMZ accounts I can see all messages, the message that the account itself spams and the message from my other NMZ host.

How is this possible? I'm running all my bots on proxies.

(sorry for unclear explanation, english is not on point)

 

Sounds like you're muted, check your offence page on your bots.

Or maybe they're using auto typer + typing? *shrug*
