The report button can be found under every single post in a thread. When you select the report button, you are reporting that specific post in which the button resides. Feel free to report if you feel that the post needs to be deleted, or edited by an admin/mod. This includes abuse, spam, anything offensive, etc.

We encourage all users to report spam. Spam when reported will flag it to every admin and moderator when they log in. The quicker we get rid of spam the better.
