For the most part we have an excellent community here with few problems as far as content goes, but occasionally something does arise.
(Usually a disagreement that devolves into an overly heated and inappropriate or pointless argument, or rivalry.)
As I'm sure everyone realises, moderators can't be everywhere at every moment. It can take some time for moderators to filter through everything and find problems, and some times thing can slip through the cracks.
For this reason, there is a "Report this post" link on every topic and reply. The button is the triangle icon with an exclamation point inside, as highlighted in the picture below:
If you see something you feel is inappropriate for the forum, please report it.
At any given time there are a lot of active topics and new replies on the forum and it takes time for moderators to cover all the ground. When a topic/reply is reported by a member, we're directly notified and can address potential problems promptly.
