Now I see it is only if there is a post. If someone starts a bogus thread without making a post, then there's no button to push-clever!
There used to be a little black 'trouble' button in the corner which we could click that allowed us to report spam or bad posts. That button does not appear anymore. At least not on my iPad.

I remember also..
Thanks for reporting it, kumquat!
