Well it looks like my Irish internet stalker has returned.
There has been some visits recently that exactly track the pattern of their often previous visits.
This time they are connecting from the Eircom network.
Whilst I do not wish to put further blocks on Irish traffic I may have to start blocking some Eircom IP ranges. I will apologise now for any inconvenience this may cause to bone-fide visitors from Ireland to this website.
Maybe more than 8 months of absence was too much to ask for.
