The list would be updated daily/weekly. The ACLs would have to be updated accordingly – this can be automated. This way 
no stale entries are present.

I block stuff all the time (like ROKSO's DROP list). The only issue with blocking domains of CPE is I imagine those 
domains change all the time as they get shutdown, if you block the IP (from domain lookup) its likely that IP maybe be 
legitimate in the future.

It should be stopped it at the DNS level, but even that has workarounds. I would think CPE is a violation of terms of 
"most" registrars.

Hello all, was curious to know the community’s opinion on whether an ISP should block domains hosting CPE (child 
pornography exploitation) content? Interpol has a ‘worst-of’ list which contains such domains and it wants ISPs to 
block it.
On one side we want the ISP to not do any kind of censorship or inspection of customer traffic (customers are paying 
for pipes – not for filtered pipes), on the other side morals/ethics come into play. Keep in mind that if an ISP is 
blocking it would mean that it is also logging the information (source IP) and law agencies might be wanting access to 
it.

Wondering if any operator is actively doing it or has ever considered doing it?

Thanks.
