Eircom did not agree to anything of the sort.
Eircom in Ireland did not agree to block any website. What they stated was that they would not contest a court case if IRMA decide to take one. A court order will be required before any website is blocked by Eircom. Do not take this as supportive of Eircom - it's not - they are a shower of spineless bastards. But misinformation doesn't help when there are plenty of legitimate examples of their ineptitude.
