Thinking out loud: using follow/unfollow you transmit a signal with no information. using the timing between the signal you are encoding symbols. I think this is called Pulse Position Modulation[0]
First step is to characterize the delta in the timestamps. That will give you an idea of what time-between-follows (TBF) should be to ensure reliable detection.
You could probably make a client for this. Build comms on top of twitter protocol.
Haven't used twitter in over 10 years, but this kinda makes me want to again.
Side note: reminds me of why gmail scans drafts. Criminals used a signal account and create drafts to communicate back and forth. This prevented detection because intel agencies scan email traffic, not drafts.
EDIT: why stop with twitter. what makes this powerful is that it leverages a feature every platform has. Youtube, Twitch, you name it. Let's go my dude.
