I'm a little confused about this part. Does the Online Safety Act create personal liabilities for site operators (EDIT: to clarify: would a corporation not be sufficient protection)? Or are they referring to harassment they'd receive from disgruntled users?
Also, this is the first I've heard of Microcosm. It looks like some nice forum software and one I maybe would've considered for future projects. Shame to see it go.
This seems very plausible to me, given what they and other moderators have said about the lengths some people will go to online when they feel antagonised.
In the same way that you could be sued for anything, I'm sure you could also be dragged to court for things like that under this law... And probably under existing laws, too.
That doesn't mean you'll lose, though. It just means you're out some time and money and stress.
Heh, welcome to the internet where the perpetrator and the beneficiary can be in different jurisdictions that make enforcement on the original bad actors impossible.
For example, have a friend in China upload something terrible to a UK site and then 'drop the dime' to a regular in the UK. The UK state can easily come after you and find it nearly impossible to go after the international actor.
