The truth is, we rely on most members' common sense to help them navigate the pratfalls of spamming. And most conversational posts are free to slide by. However, when we're talking about members who routinely make over 100 posts a day, your percentage of spam contribution shoots through the f*cking roof.
Rule of thumb? If it's not adding to the conversation in a meaningful way, or it's simply a backhanded sarcastic remark, dont bloody post it.
