In September of this year, du30newsinfo.com was observed to have at least 13 agents or spammers who posted over 4,000 posts in more than 40 groups. An account is classified as an agent or spammer if it had posted more than 100 items in groups in a single month from a single website or page alone. The 4,000 posts resulted in a cumulative 170,000-plus shares. This means that one post alone generated an average of over 40 shares. At least five of these posts received more than 1,000 shares. This is how one post can go viral very quickly.
