There is an almost infinite number of nefarious players on the Internet, all seeking similar targets, your information, your identity, your money or something else illegal / criminal. ISP's must know this. To assume they're just big, lumbering idiots who just supply a pipeline and have no clue what's going across those pipelines I would think is a silly notion. They know what ISP's help facilitate the bulk of this nonsense, yet they are not blocked. Packet sniffers could easily tell whos sending malicious content. No, we don't want Government more involved, but ISP's aren't government. Is blocking KNOWN bad Internet players suppressing freedom and free speech? Granted, I don't really know how ISP's work and what they can and cannot do so it's possible I may be missing the boat....but at least I asked and now someone can say why.
