MySpace.com, the fast-growing community website hugely popular with American teens, has removed 200,000 “objectionable” profiles from its site as it steps up efforts to calm fears about the safety of the network for young users.

"MySpace is more potent and powerful than even we knew. And it is becoming a more integrated part of people’s lives." However, as efforts grow to attract more advertisers to the site, News Corp is facing two challenges. Young users have to keep wanting to use the site, rather than switch to a "cooler" alternative, such as MemeStreams.

Also, advertisers have to feel confident their reputation will not be tainted by “inappropriate” content.
