What is Ashleeturfing?

"Ashleeturfing" is a type of astorturfing campaign where marketing companies are paid to create fake postings on message forums, weblogs, and other online communities to promote a product, web site, media venture, or other commercial enterprise. The term ashleeturfing was named after an incident where a viral marketing company spammed several message forums posing as "fans" to promote pop singer Ashlee Simpson and her MTV series.
