A man who denies running a Facebook witch-hunt against paedophiles is to be asked to reveal whether he posted a rapist's exact address, the High Court heard today.
Counsel for Joe McCloskey confirmed he will seek to provide any un-redacted version of new evidence in a potential landmark civil action.
A judge also heard claims that the campaigner was hiding material that could aid the lawsuit brought against him by a convicted child molester.
Mr McCloskey and Facebook are being jointly sued for damages by the sex offender.
The man, who cannot be identified, is claiming misuse of private information, harassment and breaches of the data protection act.
Proceedings were launched after his photograph and details appeared last year on 'Keeping our kids safe from predators II', a Facebook page administrated by Mr McCloskey.
