I never have seen spam this bad on ANY forum.
They get hammered by spawn several times a day. In the span of a few minutes the whole board fills up. Its usually dealt with pretty quickly though. You must have just showed up at a bad time. As for bookmarks, yes, its still very much a work in progress. If you'd been here just a few versions back you would have had no bookmarks at all. The feature itself is only a few months old so continue to expect improvements.
