You're on a music message board while you're at work. Forgive me if I have little sympathy for you that it's the porn that might get you in trouble.
That being said, I don't think the spam gives you the right to tell the mods to "fuck off" and to call them names when they're providing you a free service just so that you're not bored at work.
Leave the board then if it's that much of a problem for you. Like those that have come and gone before you, you won't be missed as much as you hope.
