I thought it was all a legal matter, i.e, content from your site is illegal, stealing copyright etc, then the dtails must be known (not saying you do these things, as never been to your site
) If a company wants to challenge you with the relevant body their soliceters will have to cantact you. Like ryanair did with ryanair.org.uk succsesfully and ryanaircampaign.org unsucsessfully. Hope it helps!
