No, that would be being a jerk. Even without any new rules, I would report anyone who did that. Calling someone out is, by definition, an attack, and using their trauma to do so would be beyond the pale. With a new rule, though, I will be more sure that it will be dealt with.
The scenarios you keep describing don’t seem to have anything to do with this proposed rule. You keep talking about people saying they’d be “triggered” if you posted something. That’s not what this is about. This is about using someone’s trauma or illness in order to attack them. There may be additional restrictions, but they will tell us what they are. There’s no reason to assume the new rule will be hard to follow. The whole point of such a rule is to make it clearer than it is currently.
Furthermore, this board has never been the type that lets someone get away with trying to find a loophole in the new rules. We’ve never treated the rules like a computer program that you can find an exploit in. They’re all held to a “reasonable person” standard.
No one is going to be able to say “Disagreeing with me triggers me” and have that mean that no one can disagree with them. That’s just not what’s being proposed.
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.
I get being anxious about a new rule, but nothing you have put forth seems to actually be a problem. They either misunderstand the proposed rule, or forget that the board has never allowed exploiting the rules to be a jerk.
