If I was paying per bit I would probably want my ISP to rate limit and 
firewall lots of traffic before it ever reached my pay-per-bit line.  
Otherwise I would be paying for huge amounts of unsolicited traffic from 
everywhere.

If you're comfortable that your internal audits are accurate and what 
these people are doing won't provide you any value, I don't see what 
harm it would do to block them.  Since they also have to worry about 
botnet authors blocking their traffic, I imagine they might change IP 
ranges after a while.  You might complain to them directly and see if 
they can add you to a do not poll list.  It looks like they have a 
couple of emails for issues listed here:
