I recently found the interesting example of the hoax Twitter rank creation. It is related to a numerous following Twitter action, which produces a significant number of “automatic followers”.

This means that after a time, with some number of tweet post, this account could be seen as relevant – according to number of followers.
Twitter Rank Spam Example,
Well I feel that those ppl who follow 200 ppl and hope für ppl following back… they are spamming the channel. I feel they could destroy twitter within 6 Months…
Sorry, 2000 I meant. I am also following 2000+, but I am with Twitter since dec 2006 and they kinda accumulated 😉
