People copy your habits, not your captions.

What you post is a claim and what you do is the demonstration, and people around you are running off the demonstration. They copy your sleep, your effort level at practice, how you talk about people who are not in the room. None of that gets announced, which is why it spreads so easily. The gap between the two is visible to everyone except the person standing in it.

Pick one habit you would be fine with a younger sibling copying exactly, and do that one carefully this week. Pick one you would not, and change something small about it. Say nothing about either.
