I have to admit I have been moving over to mbin. It's the same layout and hot algo but with bug fixes. I submitted an issue and they had it fixed within a few days.
kbin.social in particular only has the one admin. I keep an eye on the two ghost-town mags that I mod so they don't become spam vectors, but there's only so much we can do without an admin/dev.
It’s really frustrating because kbin has gotten too big to still basically be a one-man operation. Unless he lets other people take over some things, the wheels are gonna fall off sooner rather than later.
