This is probably a noobish question that I am simply too sleepy to figure out on my own and have likely missed, but who knows how to flag spammers?
I ask because of garbage like THIS showing up and cluttering the recent posts area on the left side of the screen. I DESPISE SPAMMERS!
Just next to the post time stamp is a link called "Flag".
Click it.
Over to the left you will now find a "reason for flag" drop down.
For spammers select "Breaks other guidelines"
Job done.
