Several boards I roam on 4chan seem to have fully recovered after the hack, with their visitor numbers back up to where they were before it happened.
What is causing /vt/, which is (was?) one of the fastest boards on the entire site, to hemorrhage users after it's return post-hack?
It's noticeably different now, much slower than it was before, you don't need to bump a thread as much to keep it alive, and once a thread hits bump limit, it takes quite a while for it to drop off the board.
