This was attempted back when Yuku actually had forums on which one could post.
For 2-3 hours every day on my board (descension.yuku.com) posts and edited posts disappear and then reappear later on. This is driving all of us insane, and it's a board-level (not a single member) type of a problem.
I have sent yuku several tickets regarding the subject, as have several of my members, yet nothing has been done and I am not even receiving a reply from whoever it is that works in the yuku offices. This has been going on for months.
