Just an FYI for those who don't know about the 'bad post report' button. The button looks like this:

and can be found to the left of each post, under the user details.

If you see a post that you think is seriously inappropriate, please use this button to report it. All admins and mods will immediately be notified about the post and why you think it is inappropriate - please note that these reports are not anonymous! That way, the problem is more likely to be dealt with quickly.

Some reasons to report a post: if you think it is spam, trollish, a personal attack on someone, racist or otherwise discriminatory, it contains obscene language or content, or if a discussion has gotten way out of hand. :

If you aren't sure, it's probably best to hang fire and keep an eye on the person or discussion before making a report.
