No porn or violence on my site, but some blocking companies block all access to certain ISPs that give free space away, could be that?

I've never liked blocking companies, proxy servers etc, I don't like the idea of someone else chosing what you get to see, if I come accross sites I find objectionable (and there is plenty out there), I click off them and don't go back. Self censorship is a far better idea. Although obviously for young kids, someone has to be responsible, but you shouldn't have to let some faceless company decide for you. Just a mild pet peave of mine.

Yup, failte is gaelic (Irish or Scots) for greetings, welcome etc.
