Recently, we had a member sign up and write a FanPost which, while it purported to be related to Cal Athletics, was really just some shameless advertising for that member's personal business. That person has been warned, and their FanPost has been deleted.
I do not relish taking actions such as this. We [the editors of this site] want it to be a place for free and unfettered discussion amongst Cal fans on a variety of subjects of common interest. Off-topic discussions, especially in comment threads, are by no means discouraged, and I personally rather enjoy them. However, advertising personal business under the guise of 'discussion' will not be tolerated, and actions similar to this will be taken.
