Facebook’s latest privacy controversy concerned user data being shared with advertisers, but it’s not the only social network to be facing such accusations. MySpace is in the line of fire, following an investigation by the Wall Street Journal – given extra spice by the fact that both are owned by News Corporation. MySpace and some of its popular apps have ben transmitting data to advertisers that could be used to identify users – their MySpace IDs, which can be used to look up their profile pages on the social network. MySpace says it doesn’t allow apps to share user IDs, and is taking action against developers who have flouted its rules. As in the Facebook farrago, the involvement of online tracking company RapLeaf seems to be a key ingredient.
