I first wrote about this block last year, but it recently came into my sights again as the host for a very widespread injection attack using the lilupophilupop.com domain.
Since last year the number of malicious sites has dropped, but there is still not a legitimate site in sight. Most of the bad sites are currently on 194.28.114.102 but you should block access to 194.28.112.0/22 (194.28.112.0 - 194.28.115.255) if you can, because this range of IP addresses is nothing but trouble.
A list of sites hosted in this range is at the end of this post, or you can download a CSV with the MyWOT ratings and IP addresses from here.
Google's prognosis of this block is pretty horrible:
