At Twitter, the act of spamming is universally panned. The first act of the Twitter Spammer is to "follow" up to 2,000 Twitterers (Twitter apparently sets the limit at 2,000 follows for new accounts). The spammer usually creates multiple Twitter accounts and spends an hour of continuous clicking following 2,000 in a big Twitter database like Robert Scoble. The spam accounts always look the same with no picture and similar name derivations:
The spammer's objective ostensibly seems to be to get Twitterers to click on their profile link (in the cases above, the link is a completely spammy website.)
Within a few hours, Twitter management suspends the site:
Twitter's Philosophical Dilemma - Explicit Spamming to Build a Following is a No No but Now it Seems Everybody wants to Build their Following Quickly
#1:Twitter started out, and continues to be viewed as a public IM tool that is shared across walled social networks. At first, philosophically, building a large Twitter network of random followers seemed to run afoul of the Twitter's implicit intention that Twitter conversations should maintain relevancy across a network, or "follower" base.
#2: Twitter users like @JasonCalacanis and others started building massive stranger networks because Twitter's unilateral "follow" clickthrough was so simple. Twitter changed the chat paradigm from private walled communication to a public broadcasting medium.
#3: Yes, spammers spend a few hours on a keyboard with the express purpose of promoting their site, and it runs counter to the social philosophy of Web 2.0. However, most Twitterers will agree that following 2,000 in one fell swoop is the quickest way to build a follower base, provided you are not suspended.
#4: As more Twitterers understand the power of Twitter as a broadcast medium, the more they start actively building their network / follower base. They look for tricks without spamming to get new followers quickly.
I notice the most efficient way to build a random follower base without spamming is to "Follow the Followers of Spammers". Since the Followers of Spammers will apparently follow anybody who follows them (including spammers), they will also follow you. It's a hidden game that many Twitterers quietly play.
Silly conclusion: Twitter spammers are part of Twitter's ecology and are here to stay.
