Genuine question, while appreciating the concern from NSC’s PoV (I think!), who is likely to be monitoring this forum to ever see this stuff, or maybe running software to bring up a combination of words like ‘Giggs and guilt’ typed by speculating football fans?
A litigious person or their lawyers, perhaps?
Granted, the risk is small, but the consequences could be the closure of the site and the possible financial ruin of the site's owner.
If you're happy to face possible bankruptcy (albeit a very low risk of doing so) so that (in the main) total strangers feel able to post libellous statements, do feel free to offer Bozza a watertight financial indemnity for, say, £500k.
As I say, the risk may be small (though I think it's higher than some other cases in this instance because of the football connection between Giggs and NSC), but the consequences could be life changing. It's just not worth the risk.
