Not sure where I heard it (Here I think..) but the magic number is something like 75Mb/s sustained. So unless you have a few thousand customers, Your most likely quite below that level. Blocking a CDN could be a big problem. You never know how much of the worlds content is CDN based till you do this. Blocking any of the big ones (Akamai, Limelight.. Bitgravity (to a lesser extent)) will break more things then you can even imagine. If someone is abusing your service, I would rate limit them.
To put it in perspective. We have two upstreams, One is prepended, making the something like 80% of the internet prefer the un-prepended transit. However, the bandwidth was almost level across the board, This had me stumped. Turns out every CDN I could find liked the prepended transit better. So even though 20% of the internet liked that transit, that 20% happened to include some of the most bandwidth intensive things around....

Akamai has a program for ISPs who use a good deal of bandwidth to their network. http://www.akamai.com/html/partners/network_program.html Basically you give them your AS (you have to be multi homed) and they see if you meet the minimum bandwidth to their network. Your upstream(s) might already be accelerated so you should make some inquiries.

It would be just about impossible to do. Netflix uses Akamai, and Hulu uses a mixture of Akamai and Limelight for "content delivery" services. These are the same content-delivery services used by just about everyone that has lots of content to distribute to lots of people (I'm pretty sure Microsoft uses Akamai for Windows Update, for instance) - Akamai claims they're responsible for 15 to 20 percent of all Web traffic on any given day, so blocking Akamai wholesale would probably be the worst idea.
