You have 101 reputation on AU, which was obtained for being a trusted user on other SE sites.
You clearly don't even use AU, so why are you posting about this here? How can you claim to have knowledge of our specific community's abilities to handle spam when you do not interact with this community?
I don't know about other SE sites, but here in AU, before the strike, our volunteer and elected moderators have been excellent at removing spam with breakneck speed.
Maybe this has been a problem on the other SEs you patron, but it has never been a problem here.
