you should post these fake messages in random intervals. If you post it every 3 seconds it could be trivial to filter the fake messages out.
How is it trivial? All messages are sent in those 3 second intervals. There are no "in between" messages. When you send a real one, it waits til the next fake one is supposed to go out and then takes its place.
Ah, oh, didn't know that. But doesn't this make the chat slow? I assume it's 3 seconds per message per group (and not per sender) so in a big group, a lot of real messages would get queued up, no?

The delay doesn't seem noticable unless you compare side by side
But it would probably get worse in a big chat with lots of people
