I think the point of many on this list is, they are a transit provider,
not a security provider. They should not need to filter your traffic,
that should be up to the end user/edge network to decide for themselves.
Additionally, content filtering is great for those type of end-user
folks, as this solution wouldn't be so difficult to scale for their
traffic volumes. However, trying to content filter a transit provider is
probably not a great idea.
