I'm a lot happier about it now Nominet have opted them back in to having their details shown in the whois since its clearly used for commercial use. It really wasn't a good idea IMHO at the time to advertise it when it was clearly breaking them initially

.
It really does seem a high number for such a small country to me and I would guess most are registered by domainers (not saying there's anything wrong with them just their sites are likely to be undeveloped/parked).
