World readable has become a liability as well. How many times has some random disagreement been blown up by observers and lead to people being kicked out of groups, jobs being lost, or SWAT raids?
I've heard of people within the argument directing SWAT raids at each other, or contacting employers, but I've not heard of it being driven by uninvolved observers.
Now... I've heard of people posting things on social media that others found offensive, and losing jobs/gigs over it, so that sorta supports what you're saying, but even in these "edgy" social media cases (which weren't "arguments" per se, in the cases I've heard about), I've not heard of SWAT/police reactions.
