>I first heard about the corona virus from 8chan. how is that possible?
Mark - along with a large portion of 8/v/ - was still clinging on to the barely-functioning 8kun because he was on Jim's payroll, and there were a few others sticking around as well (though vastly less than on 8chan proper). Virtually everyone else either stayed on their respective bunkers or went back to 4chan. Mark eventually migrated to 8chan.moe somewhere around April 2020 due to loli getting B& on 8kun

It's also possible that you're getting mixed up with Ebola-chan, which was popular in 8chan's early years and had a dedicated board

>I also remember brenton tarrant threads.
That was March 2019
