In an effort to promote teen safety, social network MySpace recently deleted 200,000 "objectionable" accounts, but the move may have been a risky one, writes Business 2.0. When Friendster - another social networking site - began removing profiles it found too risque or offensive, users ran for the exits, helping to spur rival social networks' growth, including MySpace.

MySpace may suffer similar consequences, but with 250,000 new accounts each day, the removals seem hardly able to deter MySpace's growth, according to the article.
