No I don't block them, if people using .gov wanna see my site they'd look anyway...no hiding from the govt!

As for schools, I just make sure my sites are ICRA labelled and marked as mature with meta tags, that way the kids (or the majority of kids I hope!) say out of my sites.

I always look forward to the autumn months, people in the UK head back to university and my sales start rising - those lonely boys and girls ROCK!

Loved Paco's take on this. Quality!
