Under the 'more' function, or somewhere on the page in orange is a 'report as abusive' feature.
Use this and it'll send it to the moderation queue for element14 Community staff to handle.
You can report almost all content in this way, and even user profiles.
Content gets sent to the moderation queue via two methods:
1. User Reported
2. By the system software
Staff look at the moderation queue during (at least) UK working hours of 8am to 5pm Monday to Friday and release or act on it during those hours.
