Facebook's controversial 'real names' policy has been tweaked to make it easier for people with pseudonyms or unfamiliar names to use the social network.<br />The company requries users to go by their legal or "authentic" names, which it says makes people accountable for their actions and roots out bullying.<br />However, it has been criticised by advocacy groups, who say it has discriminated against transgender people, abuse victims and ethnic minorities.<br />The policy has seen many accounts suspended because members went by a different name to the one they were born with, or just because they have been reported by online trolls.<br />Facebook accounts including a woman named Isis and Lord Toby Jug have been suspended.
