Not sure how the google search bot works in Ireland, but in the US sandboxing is very real and very frustrating to people trying to get listed on google. The general reason, I've heard at conferences, is that most web sites do not last a year, Most are put up with great expectations for 60 days and then abandoned when the expectations are not met.

Here is an example of a web site that is not indexed or been bot'ed by google. Place Stats

If you want to test this theory, put a relevant link to it and watch it get unsand boxed.
