What I posted was that people could call you out for being a liar about your condition if you started a thread about your illness that was fake, as you mentioned here.

If someone fakes a mental illness or trauma to try and garner sympathy, that’s already covered in our rule against trolling. Remember @umkay? They were banned when it was clear they were lying about their condition.
But if you’re in an argument with someone and were lying about it, you said that it doesn’t matter if you’re lying about your condition as you mentioned in the top quote in this post…
In the case of starting a thread, it matters if you’re lying about your condition to garner sympathy. In the case of arguing with someone and mentioning your trauma or condition, it doesn’t matter if you’re lying, according to your quotes.

I get being anxious about a new rule,
You’re projecting. I’m not anxious about a new rule. I’m just explaining how I see them playing out, based on my experiences with similar rules, the same as everyone else in the thread who are talking about how they see a potential new change affecting things.
