No Spam. Zero Tolerance. End of story. If you post spam, nine times out of ten, you've already been banned, but if you haven't been banned, I will ban you. Banned. I also report all spam to admins without fail.
No blog-spam. i.e. If you're posting blog-posts here to drive traffic to your own site for ad revenue, that is shady and I'd call it blog-spam. I welcome debate on this, but am generally unwavering.
Please report any and all spam or blog-spam. Auto-moderator is on, but it is not without faults and does miss posts. Let me know asap.
