Spam is a disease. It spreads like a disease. There is email spam, blog comments spam, and now Frappr spam. The Oracle Bloggers Frappr Group, and for the first time since its creation, has been hit with spam. Luckily I caught it early and deleted the spammers and their messages. So, to protect the group against spammers, I have turned on membership moderation. I have done the same for the Adobe MX bloggers group.
