“Resellers lately haven’t been selling only accounts and followers, but are now getting into the retweet business,” Mr. Stroppa and Mr. De Micheli wrote in a report. They said prices range between five retweets a day for $9 per month to $150 a month for 125 daily retweets.
The Twitter account for someone who claims to be Cilia Poon, for example, includes a bio, in Chinese, a link to a Yahoo health blog with Chinese content and has tweeted over 17,000 times — but each tweet was simply a retweet of a tweet posted by The Next Web, a technology blog (in English), that wrote about the fake Twitter follower phenomenon last December. Each time The Next Web Tweets its content, the Twitter user Cilia Poon retweets its content right away. Digging further they found several more examples of accounts that appear to exist solely to retweet content for The Next Web. (Some more convincing than others.)
Boldfaced emphasis added by me.
This has been happening for years.
How many advertisers are really addressing fake Twitter accounts?
